Appendix 179
Computer, Keyboard, and Monitor
CAUTION: Before you clean your computer, disconnect the computer from the
electrical outlet. Clean your computer with a soft cloth dampened with water. Do
not use liquid or aerosol cleaners, which may contain flammable substances.
• Use a vacuum cleaner with a brush attachment to gently remove dust from
the slots and holes on your computer and from between the keys on the
keyboard.
NOTICE: Do not wipe the display screen with any soap or alcohol solution. Doing
so may damage the antiglare coating.
• To clean your monitor screen, lightly dampen a soft, clean cloth with water.
If possible, use a special screen-cleaning tissue or solution suitable for the
monitor’s antistatic coating.
• Wipe the keyboard, computer, and plastic part of the monitor with a soft
cleaning cloth moistened with a solution of three parts water and one part
dishwashing detergent.
NOTICE: Do not soak the cloth or let water drip inside your computer or
keyboard.
Mouse
If your screen cursor skips or moves abnormally, clean the mouse. To clean a
non-optical mouse:
1
Turn the retainer ring on the underside of your mouse counterclockwise,
and then remove the ball.
2 Wipe the ball with a clean, lint-free cloth.
3 Blow carefully into the ball cage to dislodge dust and lint.
4 If the rollers inside the ball cage are dirty, clean the rollers with a cotton
swab moistened lightly with isopropyl alcohol.
5 Recenter the rollers in their channels if they are misaligned. Ensure that
fluff from the swab is not left on the rollers.
6 Replace the ball and retainer ring, and turn the retainer ring clockwise
until it clicks into place.
