Be sure to disconnect the power cord from your monitor 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
Lenovo
monitor or
any other electrical apparatus.
• Do not rub, touch, or tap the surface of the screen with sharp or abrasive
items such as a ballpoint pen or screwdriver. This type of contact may
result in a scratched picture tube.
• Do not use any type of cleaner containing an anti-static solution or similar
additive as this may scratch the screen’s coating.
• Never apply detergent or other liquid directly to the screen. Dampen the
cloth and then wipe.
Caring for your Monitor
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 10 for more
information.
Power cord
For safe operation, use the power cord supplied with the unit.
