Keyboard Cleaning; Removing The Keyboard Enclosure - NEC POWERMATE ES 5200 Service Manual

Keyboard Cleaning

As necessary, inspect and clean the inside of the keyboard as follows.
1. Remove the twelve screws holding the keyboard enclosure together (see the
figure on the following page).
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.
A – Screw (one of twelve)
2. Separate the two halves of the enclosure.
3. 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. If the board gets
wet, thoroughly dry it before reattaching the keyboard to the system unit.
4. Put the two halves of the enclosure together and secure with the screws.
