1-10 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.
