INSTALLATION & OPERATION
This trimpot is located on the lower right side of the
Format Card. The four screws holding the front panel
of the MODIIB must be removed to access the MUSIC
LEVEL control.
EMERGENCY BYPASS SWITCH:
The MODIIB contains a backup system that will keep
the show sound on the screen in the event of a failure
of the processor. This special circuitry is located on the
Mono card in the main card cage unit and is activated
by the NORMAL-BACKUP switch located just above
the Format pushbuttons.
