Typing
When you use the keyboard, follow these guidelines:
•
Adjust your seat height so that your elbows are near to your body and your forearms are
parallel to the floor. If your chair has armrests, try and use these to support your arms.
•
Type with your wrists straight and your hands floating above the keyboard. Lower your
wrists only between typing to rest them.
•
Try to avoid bending your wrists, hands or fingers sideways; if you have to press a hard-
to-reach key, move your entire arm.
•
Keep your shoulders, arms, wrists and hands relaxed. Type gently; don't bang the keys.
Viewing the Screen
Use the following guidelines to reduce eye, shoulder and neck stress:
•
Position the screen so that it is at 90° to windows, ceiling lights or other light sources.
•
Adjust the screen brightness and contrast to enhance readability.
•
Set up the screen resolution and icon and font sizes so that you can read things easily.
•
Clean the screen regularly.
•
Rest your eyes periodically by focusing on an object at least 20 feet away. Blink often.
