Ergonomic guidelines
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
on the keyboard 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.
Troubleshooting
Your mouse doesn’t work
• Make sure that the polarity of the batteries is correct. The
positive (+) and negative (-) ends of each battery must
match the positive (+) and negative (-) connections in
the battery compartment.
• Make sure that the receiver’s USB plug is firmly
connected to the USB port on your computer.
• Make sure that the appropriate device drivers are
installed.
• Make sure that you have made a radio link between the
mouse and its receiver.
