Finding Your Way around the System
Select a Place To Work
Your knees should be slightly higher than your hips. If neces-
sary, use a foot rest to raise the level of your knees and ease the
pressure on the back of your thighs.
Adjust the back of your chair so 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.
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.
Avoid bending, arching, or twisting your wrists. Keep them in
a relaxed, neutral position while typing.
Exercise your hands, wrists and arms several times during the
day to improve circulation.
