Getting Started
Selecting a place to work
❖
Position your chair so that the keyboard is at or slightly
lower than the level of your elbow. You should be able to
type 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. Do not slump forward or lean back too far.
Lighting
Proper lighting can improve the readability 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
shines directly into 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.
