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 translate to a
corresponding increase in movement
onscreen. Windows® XP has acceleration
turned on by default as a convenience for
users. However, this is on the assumption that
everyone uses 400dpi mice, so this will likely
be a hindrance to most gamers and precision
users who require greater accuracy. The
‘acceleration off’ option (default) turns off
internal acceleration only and does not 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 you 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
temperature 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 of 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 hands.

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 Lachesis™

It will record the currently-active Profile even if turned off and will boot up in the active Profile.

ON-THE-FLY SENSITIVITY™

If "On-The-Fly Sensitivity™" has been assigned to a button, pressing that assigned button and
moving the scroll wheel will produce a bar at the lower right-hand corner of your screen,
allowing you to dynamically adjust your sensitivity settings. This feature requires the driver to
be installed.
