Lighting; Arms And Wrists - Toshiba Satellite P20-8PW User Manual

If you are using a conventional chair:
■
Your knees should be slightly higher than your hips. If necessary, use
a footrest to raise the level of your knees and ease the pressure on the
back of your thighs.
■
Adjust the back of your chair so that it supports the lower curve of
your spine. If necessary, use a cushion to provide extra back support.
Lower-back-support cushions are available at many office supply
stores.
■
Sit with your back straight so that your knees, hips, and elbows form
approximately 90-degree angles when you work. Do not slump
forward or lean back too far.

Lighting

Proper lighting can improve the visibility of the display and reduce
eyestrain.
■
Position the display panel or external monitor so that sunlight or bright
indoor lighting does not reflect off the screen. Use tinted windows or
shades to reduce glare.
■
Avoid placing your computer in front of a bright light that could shine
directly in your eyes.
■
If possible, use soft, indirect lighting in your computer work area.

Arms and wrists

■
Avoid bending, arching, or twisting your wrists. Keep them in a
relaxed, neutral position while typing.
■
Exercise your hands, wrists, and arms to improve circulation.
Using the computer keyboard incorrectly may result in discomfort and
possible injury. If your hands, wrists, and/or arms bother you while typing,
stop using the computer and rest. If the discomfort persists, consult a
physician.
