Wireless Rechargeable Mouse for Desktop
• Never use the mouse on a glass or mirrored surface as
these surfaces will cause the mouse to fail temporarily.
• To maximize battery life, use the mouse on a light
colored surface. Dark surfaces cause the mouse’s light
emitter diode (LED) light to glow brighter, which
causes the battery to discharge more rapidly.
Comfortable Usage
Research suggests that physical discomfort and injury to
nerves, tendons, and muscles may be related to repetitive
motion, an improperly set up work area, incorrect body
posture, and poor work habits.
To reduce the risk of injury, follow these precautions:
• Stand, stretch, and move around several times every
hour.
• Switch hands while performing tasks. Use shortcut
keys to avoid repetitive or awkward mouse movements.
• Relax your shoulders and keep your elbows at your
sides. Adjust the keyboard’s position so that you don’t
have to stretch to reach it.
• Adjust your position so that you don’t have to bend your
wrists to type; avoid placing your wrists on a sharp
edge.
If you feel discomfort or numbness in your hands, wrists,
arms, shoulders, neck, or back while typing, consult a
qualified medical professional.
