					POWEREXEC KEYBOARD PROBLEM


PROBLEM

The PowerExec system's keyboard may experience the following two problems:

1. The keys may get "stiffer" and harder to use over time.
2. The keyboard is subject to non-working keys.


CAUSE

Friction between keys makes it difficult to type.  This friction is caused by 
environmental dirt.  There is not a problem in the design.
