remainder of the section contains removal and replacement procedures for
the field replaceable parts.

Preventive Maintenance
Preventive maintenance is limited to cleaning the plastic case, the keyboard,
and the display screen and cleaning the floppy drive heads as required.
5.2.1
Cleaning the Computer
When it is necessary to clean the plastic case and keyboard, use a soft,
lint-free cloth, slightly dampened with a mild detergent solution or use the
contents of any commercially available computer cleaning kit.
c
Caution: Never use alcohol, petroleum-based solvents, or harsh deter-
gents to clean your computer. Also never spray any liquids directly on
the computer case, keyboard, or screen. If the liquid-crystal display
(LCD) screen has become smeared or dusty, clean the screen by first ap-
plying a mild glass cleaner to a soft, clean, lint-free cloth, and gently
wipe the glass. Never apply liquids directly on the screen surface.
c
Caution: Do not use paper towels to clean the display screen. Paper can
scratch the display screen matte.
5.2.2
Protecting the Disk Drives
To protect the disk drives and data, back up the system disk periodically on
floppy diskettes. Periodically use a head-cleaning diskette in the floppy
diskette drive to prolong the life of the drive and to help maintain data
integrity.
