Advice for Health
The longer you keep using the computer equipment, the more you
become tired, which may cause disorders of your body. When you use a
computer, observe the following to keep yourself from getting tired:
Good Working Posture
Your working posture is good if the following are satisfied when you use a
computer:
• You sit on a chair with your back straight.
• Your hands are parallel with the floor when you put them on the
keyboard.
• You look at the screen slightly lower than your eye height.
No part of your body must be under excessive strain, your muscles must
be relaxed.
Your posture is bad when you sit with your back hunched up or you
operate a display unit with your face close to the screen. A bad working
posture may cause eye strain or poor eyesight.
Adjustment of the Display Unit Angles
Most display units are designed for adjustment of the horizontal and
vertical angles. This adjustment is important to prevent the screen from
reflecting bright lights and to make the display contents easy to see. You
will not be able to keep a "good working posture" and you will feel more
tired than you should if you operate a display unit without adjusting
horizontal and vertical angles.
Adjustment of Screen Brightness and Contrast
The display unit has brightness and contrast adjustment functions. The
most suitable brightness and contrast adjustment depends on the
individual and on the working environment (well-lighted room or
insufficient light). Adjust brightness and contrast so that the screen is easy
to see. An extremely bright or dark screen will have cause eye troubles.
Adjustment of the Keyboard Angle
The keyboard provided with the server is designed for adjustment to a
certain angle. Adjust the keyboard at an angle at which the keyboard is
easy to operate. The adjustment assists in reducing strain on your
shoulders, arms, and fingers.
Cleaning the Equipment
Clean the equipment regularly. It is difficult to see the display contents on
a dusty screen. Keeping your equipment clean is also important for your
sight.
Fatigue and Rest
If you feel tired, you should stop working and do light exercises.
