MAINTENANCE

This subsection contains general information for cleaning and checking the system unit,
keyboard, and LCD.
The system unit, keyboard, and LCD indicator panel require cleaning and checking at least
once a year and more often if operating in a dusty environment. No other scheduled mainte-
nance is required.

Cleaning the System's Exterior

Use the steps below to clean the outer surface of the system.
1. Power off the system and remove the primary battery pack. Unplug all cables
connected to the system.
Wipe the outside of the system unit, keyboard, and display with a soft, clean cloth.
2.
Remove stains with a mild, liquid detergent like a common household cleaner.
Use glass cleaner to clean the LCD indicator panel. Apply the glass cleaner di-
rectly to the cloth and then wipe the LCD indicator panel. Do not use solvents or
strong, abrasive cleaners on any part of the system.
Clean the keys with a damp cloth. A small, soft-bristle brush may be used to clean
3.
between the keys. Make sure to use a damp cloth (not wet) to prevent moisture
from seeping between the keypad and metal plate, possibly damaging the compo-
nents under the keys. If the keyboard gets wet, thoroughly dry it before reassem-
bling the system unit.

Cleaning the System's Interior

When servicing the inside of the system, remove dust and other foreign particles from the
inside of the system unit as follows.
Remove the top cover and keyboard using the disassembly and reassembly proce-
1.
dures later in this section.
2. Dust or vacuum (with a rubber-tipped nozzle) the inside of the system unit. Use
care to avoid damaging or dislodging any components and cables.
3. Inspect all cables connectors for damage. Ensure that connectors are seated prop-
erly before replacing the cover.
WARNING: Remove the battery and disconnect
the AC adapter before performing any mainte-
nance. Voltage is present inside the system unit
and LCD even after the system is turned off.
