8.10 Main Console Is "DEAD"
Main console is plugged in but does not respond to main console keys or customer codes. If the
main console power light is out check fuse in main console and if blown, replace. If the "power
on" light is still out check the voltage from the wall transformer. The transformer supplies
between 12 to 24VAC or DC depending on the transformer module. If the transformer is dead,
replace it. If the transformer voltage and fuse are good, there is a problem in the main PC board.
Repair or replace it.
