    					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.

    AST recommends cleaning the keyboard either by vacuuming it or by dusting it
    with compressed air.  If the problem persists, contact your local AST
