    from all persons and must not be co-located or operating in conjunction with any other

    antenna or transmitter. No change to the antenna or the device is permitted. Any change

    to the antenna or the device could result in the device exceeding the RF exposure

    requirements and void user’s authority to operate the device.


    This equipment has been tested and found to comply with the limits for a Class B digital

    device, pursuant to part 15 of the FCC Rules. These limits are designed to provide

    reasonable protection against harmful interference in a residential installation. This

    equipment generates, uses and can radiate radio frequency energy and, if not installed

    and used in accordance with the instructions, may cause harmful interference to radio

    communications. However, there is no guarantee that interference will not occur in a

    particular installation. If this equipment does cause harmful interference to radio or television

    reception, which can be determined by turning the equipment off and on, the user is

    encouraged to try to correct the interference by one or more of the following measures:

    ● Reorient or relocate the receiving antenna.

    ● Increase the separation between the equipment and receiver.

    ● Connect the equipment into an outlet on a circuit different from that to which the
