1-11    Notes on Using the 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 NEC Express 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.
