Getting Started
Placement of the computer
Position the computer and peripheral devices to provide comfort and safety.
■ Set the computer on a flat surface at a comfortable height and distance.
■ The display should be no higher than eye level to avoid eyestrain.
■ Place the computer so that it is directly in front of you when you work
and make sure you have adequate space to easily operate other
devices.
■ Allow adequate space behind the computer to let you freely adjust the
display. The display should be angled to reduce glare and maximize
visibility.
■ If you use a paper holder, set it at about the same height and distance
as the computer.
Seating and posture
The height of your chair in relation to the computer and keyboard as well as
the support it gives your body are primary factors in reducing work strain.
Refer to the following tips and to the following figure.
Posture and positioning of the computer
■ Place your chair so that the keyboard is at or slightly below the level of
your elbow. You should be able to type comfortably with your shoulders
relaxed.
■ Your knees should be slightly higher than your hips. If necessary, use a
foot rest to raise the level of your knees to ease pressure on the back of
your thighs.
■ Adjust the back of your chair so it supports the lower curve of your
spine.
■ Sit 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.
