Getting Started
Selecting a place to work
comfortably with your shoulders relaxed and your forearms
parallel to the floor.
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. Avoid slumping forward or leaning 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.
