Proper Posture During Computer Use
Chapter 1
Getting Started
21
Maintaining a proper posture during computer use is very
important to prevent physical harm.
•• Do not use the computer while you are lying down, but only
while you are sitting down.
The following instructions are about maintaining a proper posture
during computer use developed through human engineering.
Please read and follow them carefully when using the computer.
•• Do not use the computer on your lap. If the computer
temperature increases, there is a danger of burning yourself.
Otherwise, the probability of repetitive strain injury (RSI) from
repeated operations may increase and serious physical harm may
be caused.
•• Use a chair with a comfortable back.
•• The instructions in this manual have been prepared so that
they can be applied within the coverage of general users.
•• If the user is not included in the coverage, the
recommendation is to be applied according to the user’s
needs.
Proper Posture
Adjust the heights of desks and chairs appropriate to your
height.
The heights are to be adjusted so that your arm forms a right
angle when you place your hand over the keyboard while sitting
down on a chair.
Adjust the height of the chair so that your heels are comfortably
placed on the floor.
•• Work while keeping your waist straight.
•• Keep the center of your leg weight not on the chair but on
your feet when you are sitting on a chair.
•• To use the computer while talking over the telephone, use a
headset. Using the computer with the phone on your shoulder
is bad for posture.
•• Keep frequently used items within a comfortable work range
(where you can reach them with your hands).
