Working Practices
i This section gives advice on how you can work
comfortably and reduce fatigue.
Rest
Take regular breaks. Vary your posture, stand up and stretch occasionally as prolonged use of computer workstations can be tiring.
Back
Sit back in your chair and use the backrest.
Hands
Adjust the seat height so that your forearms are approximately horizontal and your wrists are straight when using the keyboard. Your upper arms should be relaxed with your elbows near your body.
Use a light touch on the keyboard, keeping your hands and fingers relaxed. Allow a space in front of the keyboard to rest your wrists when not typing. Consider using a wristpad.
Eyesight
Working with monitors, in common with any prolonged close work, can be visually demanding. Look away from the screen periodically and have your eyesight checked regularly.
Screen settings
Set the screen brightness and contrast to a comfortable level. You may have to adjust these settings as the lighting changes during the day. Many application programs let you select color combinations which can help you to view in comfort. See the User controls section on page 16 for more information.
Caring for your Monitor
Be sure to turn off the power before you perform any maintenance on the monitor. Clean your monitor as follows:
•Gently wipe the covers and the screen with a soft cloth. Do not use solvents or abrasives.
•Remove finger marks and grease with a damp cloth and mild detergent.
•Never use flammable cleaning materials to clean your IBM monitor or any other electrical apparatus.
