Operating Hints
If you are using an optical mouse, for optimal performance:
• Never use the mouse on a glass or mirrored surface or on
black velvet as these surfaces will cause the mouse to fail
temporarily.
• Avoid using the mouse on surfaces with repetitive patterns,
such as printed magazine photographs, as this type of surface
may cause the mouse to respond slowly or fail temporarily.
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, or 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.
