    General information

    Never operate the loudspeaker unattended!

    Danger of electric shock!

    To avoid the risk of electric shock, the speaker may not be opened by the

    user. There are no user-serviceable parts inside the speaker.

    Service work and repairs are reserved for qualied specialists authorized by

    Nubert. If you need service, please contact Nubert electronic GmbH directly

    ([email protected])!

    Danger of suffocation!

    Never let children use or play with neither speaker, remote control or packaging

    unattended. There is a risk that children will get caught in the packaging lm

    and suffocate. Make sure that children cannot remove any small parts from the

    devices! These parts, like the remote control battery, could be swallowed and

    cause suffocation. In case of swallowing any parts, contact a doctor immediately!

    Danger of injury or damage!

    When moving the speaker, take care to avoid injury and damage!


    Since the speaker can only be completely disconnected from the mains at the

    mains input on the rear of the unit or by pulling the mains plug from the socket, it

    must be positioned so that you have free access to the mains input or mains plug.

    If any of the following situations occurs, the loudspeaker must be switched off

    immediately and disconnected from the mains. Contact Nubert electronic GmbH

    ([email protected]) immediately!

    • The speaker has been damaged or has fallen down.

    • Power cord or plug is damaged

    • Objects or liquid have got into the loudspeaker

    • The speaker has been exposed to excessive moisture or rain.

    • The speaker does not work properly or exhibits a signicant reduction in per-


    • The loudspeaker smells burnt, develops smoke or makes unusual noises.


    The drivers built into this loudspeaker generate a strong magnetic eld in their

    immediate vicinity, which can impair or damage other devices. It is therefore

    essential to keep magnetically sensitive devices away from this loudspeaker! Do

    not place tube screens, notebooks, hard disks or the like on the speaker!

    Only use accessories recommended by Nubert!

    Low temperatures and Sound

    When speakers are shipped and delivered during the cold monthsof the year,

    it is imperative that they adapt to the temperature of the living area. Low

    temperatures have a considerable inuence on the moving parts of a loud-

    speaker such as diaphragm, voice coil,bead and spider. The ability of these

    components to follow rapid oscillations or to perform large excursions is thus

    signicantly restricted.This is not dangerous, but “frozen” speakers are far

    from their acoustic peak.

    Hence our tip: When your new speakers arrive on a cold winter’s day, just

    give them a few hours to acclimatise. Your Nubert speakers will thank you with

    the superior sound quality you have come to expect from us.

    Installation instructions


    An unstable location can damage the speaker.

    • Only place the loudspeaker on a at, stable surface and make sure that it

    cannot be knocked over!

    • Also make sure that no unintentional pulling can occur on the cables to avoid

    knocking over the speaker or damaging the connection sockets!

    • Keep strong mechanical shocks away from the loudspeaker!


    Excessive heat build-up inside the unit can shorten its service life or lead to re.

    • Never cover the back of the speaker! Make sure that there is a clearance of at

    least 10 cm and sufcient air circulation in the back area!

    • Do not operate the speaker and remote control near heat sources such as

    radiators or stoves!

    • Do not set the speaker and remote control to direct sunlight.

    • Do not expose to direct sunlight!

    • Never place burning candles or similar open re sources on the loudspeaker!

    Danger of explosion!

    Installation in unsuitable locations can cause explosions. Do not use the speaker

    or remote control

    • in environments where there is a risk of re or explosion!

    • at extremely low or extremely high temperatures!

    • near ammable gases or vapours!

    • near strong dust!

    • near ammable materials!

    Danger of electric shock!

    The loudspeaker carries mains voltage and voltages higher than 35 V AC or DC

    inside. It has no special protection against the intrusion of liquids or objects into

    the system. There is therefore a risk of lethal electric shock.

    • Never touch the speaker with wet hands!

    • Only use the speaker in a dry place!

    • Do not operate it outdoors or in damp rooms!

    • The loudspeaker must be protected from liquids of all kinds, including dripping

    and splashing water.

    Do not place any containers containing liquids (e.g. ower vases) on the speak-

    er or in the immediate vicinity!

    • If the loudspeaker is moved from a cold environment to a warm room, conden-

    sation may form inside the unit. Wait at least six hours until the loudspeaker

    has reached room temperature and is dry before switching it on!

    • No objects or foreign bodies may get into the device.

    • Should the loudspeaker come into contact with liquids or should objects have

    got inside, please unplug the mains plug immediately and contact Nubert elec-

    tronic GmbH ([email protected])!

    Danger of injury or damage!

    For speakers with threaded bushings on the underside:

    The threaded bushings may be used for upright mounting of the loudspeaker on

    suitable base plates only. The threaded bushings on the underside of the loud-

    speaker enclosures are not designed for tensile loads and must therefore not be

    used as holders for hooks or similar devices in order to suspend the loudspeaker

    cabinet. A falling speaker may cause serious injury and damage.

    Connection instructions

    General connection instructions

    • Disconnect the mains plug before changing any wiring on the system!

    • Make sure that all connections have been made correctly and that all plugs

    are rmly seated in the sockets before connecting the speaker to the mains.

    • Use only the intended cables or plug connections for the connections! Failure

    to do so may result in damage or malfunction.

    If you want to disconnect connections on the loudspeaker, always pull the plug,

    never the cable!

    • Ensure that all plugs are rmly seated in the sockets!

    • Only use cables and accessories recommended by Nubert!

    Danger of electric shock!

    Faulty mains supply systems or excessive mains voltage can lead to electric


    All power supply or antenna systems connected to the loudspeaker must com-

    ply with all applicable laws and regulations and be professionally installed by

    an approved installation company.

    • Use only the appropriate power cord to connect the speaker. Do not modify

    the power cord or its plug.

    • Make sure that the mains voltage at your location matches the requirements

    of the loudspeaker! The correct power supply can be found on the label on the

    back of the speaker. It must not be connected to other power supplies.

    • Devices of Class 1 construction must be connected to the mains power socket

    outlet with a protective earth connection. Make sure that the installation of the

    protective earth is carried out correctly!

    • When laying the power cables, make sure that they cannot be damaged (e.g.

    by heating or mechanical stress)! Pay particular attention to the areas of the

    connectors and distributors!


    Overvoltage in the power supply system (e.g. due to lightning) can damage or

    destroy the device and power supply unit.

    • An overvoltage protection element can provide a certain degree of protection

    against excessively high voltages in the power grid.

    • However, the greatest possible protection against damage can only be

    achieved with the complete separation from the mains supply.In case of thun-

    derstorms or danger of lightning strikes, disconnect the mains cable from the

    socket and any antenna plugs from your hi- system!

    • If the speaker is not used for a long period of time or is unattended, the power

    supply should be disconnected. Disconnect the mains plug from the socket!

    Remote control and battery

    This product comes with a remote control and a battery. The following must be

    observed when handling remote controls and batteries:

    If the batteries are discharged, the range of the remote control will de-

    crease signicantly. If this happens, replace the batteries immediately. Always

    use high-quality CR2025 lithium button cells as replacement batteries. Make

    sure that the polarity is correct when inserting the battery into the battery com-



    Improper handling can lead to material damage.

    • Do not drop the remote control!

    • Do not expose the remote control and battery to water or other liquids!

    • Do not operate or store the remote control and battery in locations with high

    humidity or high or low temperature!


    Leaking or exploding batteries can pose a health hazard and cause damage to


    • If you do not use the device for a long time or if the batteries are depleted,

    remove the batteries from the remote control to prevent discharge, leakage of

    acid or explosions.

    • Leaking batteries must be replaced immediately.

    • If you nd a leaking battery, do not touch the leaking material and dispose of

    the batteries immediately!

    • Do not touch leaking batteries!

    • Should your skin, eyes or mouth come into contact with the leaking material,

    clean the affected area immediately with water and contact a doctor!

    Danger! Do not ingest battery, chemical burn hazard!

    Ingestion of batteries can cause severe internal burns and death within a short

    time span.

    Ensure that batteries do not get into your body by any means, in particular that

    they cannot be swallowed!

    • Keep new and used batteries away from children.

    If the battery compartment does not close securely, stop using the product and

    keep it away from children.

    If you think that batteries might have been swallowed or placed inside any part

    of the body, seek immediate medical attention!

    Unpacking and Scope of Delivery


    Avoid using sharp or pointed objects when unpacking your speak-

    ers. Please keep the packaging in a safe place in case you need to

    transport the speaker at a later date.

    Scope of delivery

    If the delivery is complete, it contains the following parts:

    • 1 nuPro A-200 active loudspeaker

    • 1 Cloth grille

    • 1 Remote control with battery

    • 1 Mains cable, 2 m

    • 4 Signal cables:

    – Stereo jack-phono cable (3.5 mm jack), 1.5 m

    – Fibre optic cable with TOSLINK connectors, 1.5 m

    – USB cable (Type A/Type B), 1.5 m


    The nuPro A-200 are high-quality, very neutral fully active Hi-Fi/

    studio/multimedia loudspeakers (2-way bass reex system). They

    impress with an extremely homogeneous, precise, and “direct”

    sound reproduction with the nest resolution in the entire frequency

    spectrum. However, even “honest loudspeakers” are exposed to the

    manifold inuences of room acoustics. In order to achieve the most

    natural and true-to-life reproduction possible, please observe the

    following general installation instructions:

    • The rear-facing bass reex ports should be at least 3 centimetres

    away from back- and side walls in order to avoid air ow noise.

    Some distance to the back- and side walls also helps prevent an

    increase in the bass- and fundamental ranges. If the bass repro-

    duction is perceived as being too strong when the speakers are

    placed close to a wall, you can raise the lower cut-off frequency of

    the speakers, as described on page 8 under system hp, and/or ad-

    just the bass volume with the bass control as a “countermeasure”.

    When placed on a shelf, the best sound is achieved when the front

    edge of the speaker is either ush with the shelf or even protrudes

    slightly. This allows the loudspeaker to radiate the sound freely into

    the room and helps to avoid voices sounding like coming through

    a funnel.

    • On the bottom of the speaker, you will nd 4 threaded M4-bush-

    ings, 100 x 100mm apart. These are meant for mounting the

    speaker on Nubert speaker-stands or wall-mounts. You can nd

    compatible stands and wall-mounts on

    • Caution: The bushings are intended for the standing, upright

    mounting of the speaker, not for hanging the speaker from the

    ceiling or any other tensile loads!

    • Within listening angles up to 30 degrees off the horizontal axis,

    you will experience no signicant change or loss in sound quality.

    Only at wider listening angles does the sound lose its brightness

    slightly. It is then advisable to point the speakers towards the lis-

    tening position or – if this is not possible – use the treble control to

    brighten the sound a little.

    • The most natural sound is achieved when the tweeter is at about

    ear level. But even 20 degrees above the tweeter axis, the sound is

    still homogeneous. If your active speakers need to be placed lower

    or higher, they should be angled so that the tweeters are aimed at

    the listening position.

    Cloth grille

    The cloth grille protects the loudspeaker drivers (for example from

    curious children who like to press in tweeter domes) and provides a

    visual contrast for those who do not like the technical appearance

    of loudspeaker drivers. It is carefully placed against the front of the

    speaker and held in place magnetically. Please make sure that the

    surface of the bafe is not damaged.

    With the cloth grill removed, the loudspeaker sounds somewhat

    brighter and clearer – the choice is yours

    When handling the remote control:

    Make sure the battery is inserted correctly, observing the polarity

    of the battery. If you need to replace the battery, always use a high

    quality CR2025 battery.

    Remote Control

    Construction and technology

    Tilt Control

    The midrange/treble adjustment of the nuPro loudspeakers has the

    characteristics of a so-called “Tilt control”. While standard treble

    controls “bend” the frequency response and thus produce colour-

    ations, this control continuously affects the frequency response in

    a linear fashion. This perfectly preserves the basic tonal character

    of the loudspeaker and the harmony of the sound image. The Mid/

    Hi tone control allows an increase or decrease of the frequency

    response with a maximum of 12 dB at 20 kHz.


    After being powered on, the nuPro speaker sets the input sensitiv-

    ity automatically. For this reason, it is important that you connect

    your sources and let them play for few seconds before switching

    the nuPro on. If the voltage of the signal increases too much dur-

    ing playback, the input sensitivity is automatically lowered. You can

    deactivate this function in the menu (see page 8, section “AGAIN”).

    Digital Signal Processing

    For maximum delity, the signal path of a nuPro loudspeaker is

    kept entirely digital: Digital input signals go straight to the digital

    signal processor (DSP), which then performs crossover functions

    and optimization of the frequency response. Analogue sources are

    rst converted to a digital signal by high-quality A/D converters.

    The signal remains digital all the way into the power ampliers for

    best possible precision and signal to noise ratio.

    Latency compensation

    Due to the digital signal processing, a slight delay is introduced,

    so-called latency. If you connect additional nuPro loudspeakers to

    the link-output, this delay is automatically compensated for in order

    to ensure the best possible time-alignment. The result is an optimal

    stereo image with precise voice location (see page 9, section “fur-

    ther applications").

    Sound format

    The digital inputs of your nuPro loudspeakers accepts PCM-format

    signals only. It may therefore be necessary to adjust the settings of

    players such as TV sets or game consoles accordingly. To do this,

    select “PCM” as the output format in the playback menu. Please

    refer to the manual of your source device.

    Switching off a pair of nuPros

    If the master speaker switches to stand-by mode (due to automatic

    switch-off or manually with the remote control), the other speakers

    operated in PAIR mode follow automatically. However, since these

    speakers now receive no control signal for a short time, they briey

    switch to SINGLE mode before switching off and show this in the

    display. This is normal and does not affect the function of the nu-

    Pros in any way.

    If, however, the remote control's stand-by button is pressed again

    during the power down process, the speaker may in some cases

    remain in SINGLE mode. In this case, it may be necessary to turn

    on the box one at a time. To do this, press the  button while the

    master box is switched on.

    Auto-on/off function

    The auto on/off function reacts differently, depending on the select-

    ed input: If no signal is present at the analog input, the loudspeaker

    is switches to stand by after 20 minutes. As soon as an analog

    input signal is detected, the speaker switches back on. At the other

    inputs, the activity of the connected source is monitored, allowing

    the loudspeaker to switch off or on instantly. At the SPDIF and Op-

    tical digital inputs, the presence of the digital data stream is moni-

    tored, while at the USB input the presence of USB supply voltage

    is detected.

    The auto-on function is only active if the loudspeaker was set to

    standby by the auto-off function. To wake up the loudspeaker, a

    signal must be present at the input that was selected when the

    loudspeaker went into standby

    Note: Modern computers often have USB sockets that deliver con-

    stant voltage (e.g. for charging a mobile phone) even when the

    computer is switched off. If you want to use the auto-on function of

    your nuPro active loudspeakers in conjunction with the USB input,

    you must use a USB connector that powers off with the computer.

    Remote control signals, AS-250 and the nuPro A-series.

    The remote-control signals of the AS-250 and the nuPro A-series

    loudspeakers do not cause interference with each other, making

    it possible to use combinations of these systems without acci-

    dentally operating the wrong speaker.

    nuPro A-200

    · 4/2020 EN

    When the nuPro are powered on, they automatically congure

    themselves as as Master- or Slave-loudspeaker, depending on the

    cabling. They are now ready for use. For more on the basic cong-

    uration of your nuPro speakers, please see the separate quickstart


    All settings can be adjusted and read using the keypad and display

    on the front of the speaker. After 8 seconds of inactivity, the display

    changes back to its default readout (default: level). Pressing a key

    will take you to the last used menu or let you adjust the volume.

    Pressing  in the volume menu will access the main menu.

    Pressing this key will always take you back to a higher menu


    By pressing  or  you can access the different menus and

    change their settings.

    By pressing  you will enter a sub-menu. Pressing the MENU

    key in the middle will conrm a selection you have made or

    conrm the choice of a sub-menu.

    Note: Your settings are saved when the display changes back to

    its default state. If power to the nuPro speaker is lost before this

    happens, the speaker will load the last saved state when power is

    n CHANNL (Channel)

    Here you can specify whether the respective nuPro should play the

    left (LEFT) or right (RIGHT) channel. If you want the loudspeaker

    to reproduce a mono signal, this can also be set here. Note: This

    menu item is only available in the SINGLE conguration, see section


    n MID HI (Mid/High)

    Use the  and  keys to raise or lower the mid/high level by up to

    12 dB. See also page 7, section “Tilt control”.

    n BASS

    Use the  and  keys to raise or lower the bass level by up to

    12 dB.

    n BAL (Balance)

    Use the  and  keys to change the relative level between the left

    and right channel by up to 9 dB.

    n SUBOUT

    The subwoofer output outputs a low-passed mono sum signal. In

    this menu you can set the desired crossover frequency for the sub-

    woofer. Use the  and  keys to change the crossover frequency.

    Note: The output sub out always outputs a mono signal formed from

    the signal of the current source device.

    n SYS HP (High-pass and crossover frequency)

    In this menu, you can set the high-pass (lo-cut) lter frequency.

    This is particularly useful if you connect a subwoofer to your nuPro


    Use the  and  keys to activate (ON) or deactivate (OFF) the

    lter. If the Filter is set to ON, press  or the MENU key to get to

    the next menu where you can set the proper frequency, using the

     and  keys

    Note: Setting the high-pass lter to a higher frequency increases

    the maximum possible sound pressure level from your nuPro loud-


    n SETUP

    This menu item is used to select the operating mode.

    If you operate your nuPro active loudspeakers as a stereo pair,

    select pair for both speakers. This is also the factory setting. The

    speakers thus congure themselves automatically as slave and

    master. Both speakers can be operated from the master speaker


    If you want to freely congure your boxes individually, you can select

    the menu item SINGLE here. You now have access to the complete

    conguration of the speaker box.

    Note: In the SINGLE conguration, the box outputs the selected

    input signal completely in SPDIF format at the link output. In PAIR

    mode, only one channel is output.

    n DISPLY (Display)

    After 8 seconds of inactivity, the display reverts to its default readout.

    The DISPLY menu allows you to change this readout. You can set

    the display to display the level (VOLUME), the nuPro logo (LOGO)

    or turn the display off (OFF).

    n LIM DS (displaying limiter/overload protection status)

    Each nuPro loudspeaker has a built-in, always active protection cir-

    cuit, which reliably protects the drivers from overload. If the built-in

    overload protection is active, this is indicated in the display by the

    word LIMIT. In this menu, you can choose to have this warning-mes-

    sage displayed (ON) or not (OFF).

    Note: The display starts already with very small reactions of the

    limiter – long before a limiting effect is audible.

    n PRESET

    In this menu, you can save all settings of the nuPro speaker in three

    presets. To do this, select the preset slot you want to save in, us-

    ing the  and  keys, then press the MENU button until the word

    SAVING appears in the display. To recall a preset, select it in the

    menu and conrm with a short press of the central MENU button.

    LODING is then briey shown in the display to conrm the selection.

    n AUTO

    The electronics of the nuPro speakers has an automatic stand-by

    function, which automatically switches the loudspeaker to stand-by

    and back on as required. Selecting OFF disables this function.

    Further information on the automatic stand-by function can be found

    on page 7 in the “ Construction and technology” section.

    n AGAIN (Autogain)

    By default, the input sensitivity of your nuPro speaker is set automat-

    ically to avoid overload and distortion. If you don’t want to use this

    feature, select OFF in this menu. The input sensitivity is then xed

    at 1,5 V. See also Page 7, “construction and technology”.

    n DEFALT (default)

    In this menu you can reset the speaker to factory settings. To reset

    your speaker, select OK and conrm by pressing the MENU key.

    LODING is then briey shown in the display to conrm the reset.

    Note: You can also reset the speaker by pressing and holding the

     key for 8 seconds.

    Further use-cases

    Adding a subwoofer

    If you want to add a subwoofer to your nuPro speaker, you can

    connect it to the sub out output. This output provides the subwoof-

    er with a low-pass ltered, summed mono signal. You can set the

    crossover frequency for the subwoofer in the menu advan-ced /

    subwoofer.The cut-off frequency for the nuPro speaker is adjusted

    in the SYS HP menu (see page 8). The relative level of the sub-

    woofer must be set on the subwoofer itself.

    Single-speaker applications

    When delivered, each nuPro reproduces the left channel of a ste-

    reo signal and can thus be operated without any problems. Howev-

    er, if it is to reproduce a mono sum signal, the following congura-

    tion must be done:

    Select SINGLE in the SETUP menu item. Then you can navigate

    to the CHANNL menu item and select the MONO entry. (For more

    information, see also page 8)

    Multi-speaker applications

    (see illustration below)

    To supply a larger number of nuPro active loudspeakers with the

    same signal, the connection from link out to spdif in can be per-

    formed repeatedly. In this case it is recommended to congure

    each nuPro individually and therefore to select the entry SINGLE

    in the menu item SETUP. Then you can navigate to the menu item

    CHANNL and select the channel that the respective nuPro should

    play back. (For further information see page 8).

    Note: In the SINGLE conguration, the link-output outputs the se-

    lected input signal as an SPDIF signal, making it possible to dai-

    sy-chain a virtually unlimited number of speakers.

    Connecting a nuPro pair to a preamplier

    In addition to connecting a preamplier to a nuPro pair in master-

    slave mode, an external preamplier can also be connected directly

    to each individual nuPro active loudspeaker. As with conventional

    active loudspeakers without master-slave functionality, the boxes

    can then be congured independently of each other. Connect the

    output of the left channel of your preamplier to the nuPro on the

    left and the output of the right channel to the nuPro on the right.

    Note: Use the left input (aux L) of each nuPro speaker. Do not con-

    nect the loudspeakers to each other with the SPDIF coaxial cable.

    Care and cleaning tips


    Improper handling of the speaker may result in damage.

    • Always unplug the speaker before cleaning it!

    • Before recommissioning, make sure that all connections are cor-

    rect, that there are no short circuits and that the speaker is com-

    pletely dry.

    • Never use strong cleaning agents or solvents such as petrol, spir-

    it or similar!


    We recommend commercial window cleaner sprayed onto a cotton

    cloth. This allows almost all ngerprints and dust to be easily re-

    moved. Alternatively, you can also use window active foam.

    We advise against the use of microbre cloths! These can cause

    mini scratches in the surface.

    Diaphragms and Speaker Chassis

    To remove dust from a loudspeaker chassis, a lint-free cotton cloth

    is sufcient to wipe the membrane lightly with very little pressure.

    The tweeters of all Nubert loudspeakers are equipped with a pro-

    tective grille so that they can also be wiped off with low pressure. If

    the dust cannot be completely removed, a make-up brush from the

    drugstore is suitable.


    If you have any questions or problems during the commissioning of

    your Nubert system, please do not hesitate to contact our service

    Nubert warrants the Nubert product described in this manual to the purchaser under the following terms and conditions.

    The purchaser‘s statutory warranty claims, in particular for subsequent performance and, if applicable, damages in the event of defects, shall remain unrestrictedly with the

    purchaser and shall be fully available to our customers.

    1. The warranty period for the Nubert product and its electronic components described in this manual is 2 years from the date of delivery.

    Your proof of purchase is the proof of guarantee.

    2. Contents of the warranty claim

    The guarantee applies to all parts and labour costs from delivery. It includes and is limited to the free repair or replacement of the defective part in the event of a material

    defect in the goods (e.g. Material defect or manufacturing defect). In addition, Nubert shall bear the costs of the return shipment of the affected product from or to the curb

    in the case of justifi ed warranty claims, provided that the goods are within the countries of the European Union and the shipment was previously agreed with Nubert. Ad-

    ditional services are possible as a gesture of goodwill in accordance with Nubert’s free discretion. For the duration of the guarantee, it is assumed that the material defect

    was already present at the time of transfer of risk. Replaced parts become the property of Nubert. Warranty services do not extend the warranty period, nor do they set a

    new warranty period in motion. The warranty period for installed spare parts ends with the warranty period for the entire device. The promise or the execution of warranty

    services is made without recognition of a performance obligation according to statutory warranty law.

    3. The warranty claim does not apply in the case of

    • repair attempts of any kind not previously agreed upon with Nubert

    • improper operating environment or improper storage (e.g. damage due to moisture or particularly high or low temperatures)

    • improper transport packaging (the original transport packaging, correctly used, provides suffi cient protection)

    • improper transport, if the transport was not previously agreed upon with Nubert (Nubert organizes the transport for you with Nubert selected

    Transport company. You will receive return tickets with the corresponding postage paid returns).

    • improper mechanical effects on the goods (e.g. on housing, switches, connection sockets or antennas)

    • improper operation, improper mounting (e.g. switches, antennas) or improper connection (e.g. operation on defective or unsuitable amplifi ers or other source devices

    with DC voltage or unusually high hum voltage at the source device output).

    4. Disassembled components

    Do not disassemble any components from our equipment and do not send in any such individual parts until you have contacted Nubert Service and agreed on this measure.

    5. What to do in the event of a warranty claim

    If possible, pack the defective device in its original carton with a copy of the purchase receipt and a meaningful description of the defect. Please note our shipping instruc-

    tions. Please contact the Nubert team for a return or refund:

    • Telephone within Germany 0800-68 23 780 (toll free) • Phone international: +49 7171 92690-118 • Fax: +49 7171 92690-145 • E-mail: [email protected]

    Of course, you can also return your defective product to the Nubert Service in Schwäbisch Gmünd or Aalen:

    • Nubert electronic GmbH, Goethestr. 69, D-73525 Schwäbisch Gmünd, Germany • Nubert electronic GmbH, Bahnhofstr. 111, D-73430 Aalen, Germany.

    Shipping information: We recommend that you always keep the original carton, along with the protective foam inserts. Tip: Folding saves space! This is the only way to

    ensure a safe return shipment in the worst-case scenario. If, in exceptional cases, you use a different packaging, it should protect professionally against the typical dangers

    of shipping and have special protective cushions or equivalent protective devices. We would like to draw your attention to the fact that we accept no liability for damage

    caused by improper packaging for which you are responsible!

    Disposal and battery return

    Environmental protection: Ingredients, e.g. chemical pollutants in old appliances, can damage the environment and health if stored improperly, in particular if they are

    not shatterproof or disposed of properly by persons not authorised to do so. Especially in the case of illegal exports, there is no guarantee that the environment and human

    health will be protected from damage. Old appliances can also contain recyclable raw materials, old appliances can be repaired or parts can be reused and thus considera-

    bly protect the environment. Old appliances must therefore not be disposed of with normal household waste or exported illegally. As an end user, you are legally obliged to

    return or properly dispose of electrical equipment.


    Ingredients, e.g. chemical type of batteries, can damage the environment and health if not stored and disposed of properly. At the same time, recyclable raw materials may

    also be included. Batteries must therefore not be disposed of with normal household waste. As an end user, you are legally obliged to return used batteries. You can return

    batteries after use to the seller or in the designated collection points (e.g. in public collection points in your municipality or in the trade) free of charge or send them back

    free of charge. You can also send the batteries back to the seller free of charge by post, whereby any requirements of the dangerous goods law must be observed. The sale

    at points of sale is limited to the quantities customary for end users for disposal as well as used batteries which the distributor carries or has carried in its product range.

    • Battery return

    The symbol with the crossed-out dustbin reminds you not to put batteries in the household waste.

    Under this symbol you can also fi nd the following symbols with the following meaning about ingredients:

    Pb = battery contains more than 0.004 mass percent lead, Cd = battery contains more than 0.002 mass percent cadmium,

    Hg = battery contains more than 0.0005 mass percent mercury.

    • Old appliances

    Electrical and electronic equipment is also marked with the crossed-out wheelie bin symbol. The symbol indicates that you,

    as the owner of this appliance, may not dispose of it with your household waste (grey bin, yellow bin, organic waste bin, paper or glass).

    You can send the device to the municipal collection points to be collected separately from unsorted municipal waste for reuse. Used batteries and accumulators which are

    not enclosed by the waste equipment shall be separated from it at a collection point prior to delivery.

    Old appliances can also be returned to us directly in our shops or shipped back to us for disposal. Please send an Email to [email protected] for a free return shipping label.

    You can also request this by calling +49 7171-92690118. Please then send the old device to the following address:

    Nubert electronic GmbH, Goethestr. 69, D-73525 Schwäbisch Gmünd, Germany.

    Please ensure that the old appliance is properly packaged for shipment so that breakage is avoided as far as possible and mechanical compaction or breakage can be ruled

    out. The acceptance of waste equipment may be refused if there is a risk to human health and safety due to contamination.

    Please note: You are responsible for the deletion of personal data on the waste equipment to be disposed of.
