4-2 Maintenance and Troubleshooting
MAINTENANCE
This subsection contains general information for cleaning and checking the system, keyboard,
and monitor.
The system, keyboard, and monitor require cleaning and checking at least once a year, and more
often if operating in a dusty environment. No other scheduled maintenance or
lubrication is required.
WARNING:
Unplug all power cords before per-
forming any maintenance. Voltage is present inside
the system and monitor even after the power button
is off. All voltage is removed only when the power
cord is unplugged.
System Cleaning
Use the following procedure for cleaning the system.
1.
Power off the system and unplug all power cables.
2.
Periodically wipe the outside of the system, keyboard, mouse, and monitor with a soft,
clean cloth. Remove stains with a mild detergent. Do not use solvents or strong, abra-
sive cleaners on any part of the system.
3.
Clean the monitor screen with a commercial monitor screen cleaning kit. Or use a
glass cleaner, then wipe with a clean lint-free cloth.
4.
Local distributors and dealers may sell diskette drive head cleaning kits. These kits
contain special diskettes and cleaning solution. Do not use the abrasive head cleaning
kits (kits without cleaning solution). Insert the diskette immediately after powering on
the system, before the disk boot-up. Allow the diskette drive heads to clean for about
30 seconds.
