Maintenance and Troubleshooting 4-7
WARNING:
Unplug all power cords before
performing 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, abrasive 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.
Keyboard Cleaning
When necessary, inspect and clean the inside of the keyboard as follows:
1.
Turn the keyboard upside-down.
2.
Remove the screws holding the keyboard enclosure together.
NOTE:
The keyboard and cable together are
considered a whole-unit, field-replaceable
assembly. Therefore, disassembly of the
keyboard is necessary only when cleaning the
inside.
3.
Separate the two halves of the enclosure. Clean the enclosure and keys with a
damp cloth. A small, soft-bristle brush may be used to clean between the keys. Do
not wet or dampen the keyboard's printed circuit board (PCB). If the PCB
accidentally gets wet, thoroughly dry it before reattaching the keyboard to the
system unit.
