Diagnostics
Introduction
This section of the manual provides information to assist you in isolating faults
that may occur in the Control Panel and Signal Processing Frame. For safety,
service should only be performed by qualified personnel.
The information is organized to allow for quick diagnosis and isolation of system
faults to a circuit module level only. When the suspected circuit module is located
it should be replaced with a spare or sent to your nearest GVP Customer Service
facility for module swap.
CAUTION
Multi-layer printed circuit manufacturing and surface mount technology (SMT)
techniques have been used in the manufacture of many of these circuit modules.
Specialized equipment and training are required to properly repair them.
Attempting to repair circuit modules rather than replacing them, as recommended,
can result in potentially expensive damage that is not covered under warranty.
Later versions of the system software will include software diagnostic routines to
further assist you in quickly locating and correcting faults.

Dangerous voltages are present even with the AC power switch in the Off
