1-16 Notes on Using Your Server
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
You have good posture 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.
You have "good working posture" as described in the above when no part
of your body is under excess strain, in other words when your muscles are
most relaxed.
You have "bad posture" when you sit with your back hunched up or you
operate a display unit with your face close to the screen. Bad working
posture may cause eye strain or poor eyesight.
Adjustment of 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 "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 depend on the individual and the
working environment (well-lighted room or insufficient light). Adjust
brightness and contrast so that the screen will be easy to see. An
extremely bright or dark screen will give a bad effect to your eyes.
Adjustment of Keyboard Angle
The keyboard provided with the server is designed for adjustment of an
angle. Adjust the keyboard angle at which the keyboard is easy to operate.
The adjustment assists in reducing strain on your shoulders, arms, and
fingers.
Cleaning of Equipment
Clean equipment regularly. It is difficult to see the display contents on a
dusty screen. Keeping equipment clean is also important for your sight.
Fatigue and Rest
If you feel tired, you should stop working and do light exercises.
