6-2 Preventive Maintenance
This section contains general information for cleaning and checking the
PowerMate 2000 system.
The system unit, LCD panel, keyboard, and mouse require cleaning and
checking at least once a year, and more often if operating in a dusty
environment. No other scheduled maintenance is required.
Unplug all power cords before performing any maintenance.
Voltage is present inside the system even after the power 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 the AC power adapter cable.
2.
Wipe the outside of the system, keyboard, mouse, and LCD panel 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 LCD panel screen with a commercial monitor screen cleaning kit.
As an alternative, use a glass cleaner, then wipe with a clean lint-free cloth.
4.
Local distributors and dealers 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 disk
bootup. Allow the diskette drive heads to clean for about 30 seconds.
Keyboard Cleaning
As necessary, inspect and clean the inside of the keyboard as follows.
1.
Turn the keyboard over and remove the screws holding the keyboard
enclosure together.
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.
2.
Separate the two halves of the enclosure.
