2. Safety check out
(U.S.A. model only)
After correcting the original service problem, perform the following safety check before releasing the unit to the customer.
Leakage current Check
Measure the leakage current to a known earth ground (water pipe or conduct etc.) by connecting a leakage current
tester between the earth ground and exposed metal parts of the unit (inpquutput ground terminals, screw heads or metal overlays etc).
Plug the power supply cord directly into a l20Vac 601-12 wall socket and turn ON/STANDBY button on.
Any current measured must not exceed 0.5mA.

3. To initialize the unit
1. Press ON/STANDBY button while pressing down CBL/SAT button when the unit is POWER ON, then the FL displays
"CLEAR", and turn to STAND-BY.
Preset memory and each mode stored in the memory, are initialized and will return to the factory settings.

Clear 6 Stand-by

2. Remove power cord from wall outlet.
