Adjustment and Test Point Layout

Service Adjustment Notes:

Caution: The B8 Chassis incorporates a "Hot" ground system. Always use a
separate isolation transformer when applying power to the exposed chassis.
Unless Otherwise Specified:
1. All service adjustments are "Hot" voltagewise. For maximum safety, ensure the use
of properly insulated tools.
2. Many of the following adjustments are made through software intervention. The
remote transmitter supplied with the set may be used in order to modify register
values stored within the EEPROM IC on the Main Chassis Board Assembly. The
G96SVC Service Remote is an ideal tool for this purpose. Order 4835 219 17656.
Refer to the SERVICE MODE covered later.
3. Refer to the Component Location Diagram (Figure 1) for a quick location of test
points or service adjustable controls.
4. Grid locations (Ex.: D-2) next to control reference numbers refer to the Main Chassis
Printed Circuit Board Illustrations.
