1. Replacing the fuses
This symbol located near the fuse indicates that the
fuse used is slow operating type, For continued protection against
fire hazard, replace with same type fuse, For fuse rating, refer to
the marking adjacent to the symbol.
Ce symbole indique que le fusible utilise est e lent.

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 (input/output ground terminals, screw heads or metal overlays etc.).
Plug the power supply cord directly into a 120Vac 60Hz 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.
2. Remove power cord from wall outlet.

5. Notes on repairs (Power supply board)
Some parts on BAPS-1120 may remain high voltages
even after the power cord is disconnected from AC power source.
Before starting repair and any other work , please discharge C9002 by connecting resistors between its terminals. See the figure below
(recommended resistor spec: 5 k ohms/ 10W)
It is dangerous to touch the "HIGH VOLTAGE PRIMARY" area surrounded by white lines without discharging.
The operations of DSP and DIR etc are able to checked by the information displayed on FL in this debug mode.
This information will help to analysing digital audio no sound trouble.
To set in Debug mode
1. Press and hold down DISPLAY button, then press ON/STANDBY button.
2. Press + (TONE) button while the version number of microprocessor is displayed.
