Appendix B Safety, Use, and Care Information 79

Mouse

Place the mouse at the same height as the keyboard and within a comfortable reach.

Keyboard

When you use the keyboard, your shoulders should be relaxed. Your upper arm and

forearm should form an angle that is slightly greater than a right angle, with your wrist

and hand in roughly a straight line. Use a light touch when typing and keep your

hands and fingers relaxed. Avoid rolling your thumbs under your palms.

Change hand positions often to avoid fatigue. Some computer users may develop

discomfort in their hands, wrists, or arms after intensive work without breaks. If you

begin to develop chronic pain or discomfort in your hands, wrists, or arms, consult a

qualified health specialist.
