Sensitivity 
Mouse sensitivity is an internal filter of the 
driver. The maximum sensitivity setting of 10 
is unfiltered. Each incremental stop or setting 
is a 10% decrease, i.e. Setting 1 will decrease 
mouse pointer input to 10% (i.e. a linear graph).
Acceleration
Acceleration is an internal filter of  the driver, 
and is primarily a legacy option  for low dpi 
mice users. With acceleration enabled,  how 
fast you swipe the mouse will tra nslate to a 
corresponding increase in movement 
onscreen. Windows® XP has acceleration 
turned on by default as a conveni ence for 
users. However, this is on the a ssumption that 
everyone uses 400dpi mice, so thi s will likely 
be a hindrance to most gamers and  precision 
use
rs who require greater accuracy. The 
‘acceleration off’ option (default ) turns off 
internal acceleration only and does no t affect 
Windows® XP acceleration, which can  be 
turned off via the Control Panel  > Mouse > 
Pointer Options, and unselecting  the ‘Enhance 
Pointer Precision’ option.
Windows® Pointer Speed
Pointer speed refers to the Windows® 
implementation of sensitivity. In Windows® XP, 
a setting of ‘5’ means there is no filtering 
(default). This section has been included for 
user convenience.
DPI Switcher – Resolution
Resolution refers to the number of counts per 
inch of movement sent by the mouse hardware to 
the OS. E.g. 500dpi means that a movement of 
one inch 
will result in 500 counts of movement. 
Without any of the above filters operating, this 
will result in 500 pixels of movement on the 
screen.
Independent X- and Y-Axis Settings
You can preset the X-axis (horizontal) and Y-axis 
(vertical) sensitivity levels independently. When 
this feature is enabled, a new on-the-fly 
interface bar will appear onscreen to allow 
further sensitivity adjustments.

Safety Guidelines
In order to achieve maximum safety while using 
your Razer Lachesis™, we suggest that you 
adopt the following guidelines:
1.  Avoid looking directly at the laser beam of 
your Razer Lachesis™ or pointing the beam 
in anyone else’s eye. Note that the laser 
beam is NOT visible to the naked human eye 
and is set on an Always-On™ mode. 
2.  Should y
ou have trouble operating the mouse 
and troubleshooting does not work, unplug 
the device and call the Razer™ hotline or go 
to www.razerzone.com for technical support. 
Do not attempt to service or fix the device 
yourself at any time.
3.  Do not take mouse apart (doing so will  void 
your warranty) and do not attempt to service 
it yourself or operate it under abnormal 
current loads. 
4.  Keep mouse away from liquid, humidity  or 
moisture. Operate it only within the specified 
temperature range of 0˚C(32˚F) to 
40˚C(104˚F). Should you operate it in a 
temperature that is beyond this range, 
unplug and switch off the device to let the 
tempe
rature stabilize within the optimal 
temperature range. 
COMFORT 
Research has shown that long periods of 
repetitive motion, improper positioning of your 
computer peripherals, incorrect body position, 
and poor habits may be associated with physical 
discomfort and injury to nerves, tendons, and 
muscles. Below are some guidelines to avoid 
injury and ensure optimum comfort while using 
your Razer Lachesis™ .
1.  Position your keyboard and monitor directly in 
front of you with your mouse next to it. Place 
your elbows next to your side, not too far away, 
and with your mouse within easy reach.
2.  Adjust the height o
f your chair and table so 
that your keyboard and mouse are at or below 
elbow height. 
3.  Keep your feet well supported, posture 
straight and your shoulders relaxed.
4.  During gameplay, relax your wrist and keep 
it straight. If you do the same tasks with 
your hands repeatedly, try not to bend, 
extend or twist your hands for long periods. 
5.  Do not rest your wrists on hard surfaces for 
long periods. Use a wrist support such as 
the gel-filled Razer eXactRest™ to support 
your wrist while gaming.
6.  Customize the buttons on your Razer 
Lachesis™ to suit your style of gaming in 
order to minimize repetitive or awkward 
motions while gaming. 
7.  Make sure that your Razer Lachesis™ fits 
comfortably in your h
ands.
8.  Do not sit in the same position  all day. Get 
up, step away from your desk and do 
exercises to stretch your arms, shoulders, 
neck and legs. 
9.  If you should experience any physical 
discomfort while using your Razer 
Lachesis™, such as pain, numbness, or 
tingling in your hands, wrists, elbows, 
shoulders, neck or back, please consult a 
qualified medical doctor immediately.
 
MAINTENANCE AND USE
The Razer Lachesis™ is equipped with a laser 
sensor, which has a tracking beam that is 
invisible to the naked human eye. There is a 
little regular maintenance required to keep it 
in optimum condition. Once a month we 
recommend you unplug your Razer Lache
sis™

underneath with a soft cloth or cotton swab. 
Use a little warm water but no soap or harsh 
cleaning agents.
To get the ultimate experience in movement 
and control, we highly recommend a premium 
mousing surface from Razer. Some surfaces 
will cause undue wear on the feet requiring 
constant wear and eventual replacement. 
Please note that the sensor of Razer Lachesis™ 
is ‘tuned’ or optimized especially for Razer™ 
mousing surfaces. This means that the sensor 
has been tested extensively to confirm that the 
Razer Lachesis™reads and tracks best on 
Razer™ mousing surfaces. Other premium 
mousin
g surfaces from companies like 
Everglide™ may work just as well.
