1.2. Before Use (For PH only)
Be sure to disconnect the mains cord before adjusting the voltage selector as shown in Figure 1-2.
Use a minus(-) screwdriver to set the voltage selector (on the rear panel) to the voltage setting for the area in which the unit will be
used.
Note that this unit will be seriously damaged if this setting is not made correctly. (There is no voltage selector for some countries,
the correct voltage is already set.)

1.3. Before Repair and Adjustment
Disconnect AC power to discharge the capacitor (in SMPS Module) as indicate below diagram through a 10
Ω
, 10 W resistor to
ground.
Caution:
DO NOT SHORT-CIRCUIT DIRECTLY (with a screwdriver blade, for instance), as this may destroy solid state devices.
After repairs are completed, restore power gradually using a variac to avoid overcurrent.
Current consumption at AC 110~127 V / 220~240 V, 50/60 Hz in Power ON, FM Tuner at volume minimal mode should be ~ 450
mA (PH).
Current consumption at AC 120 V, 60 Hz in Power ON, FM Tuner at volume minimal mode should be ~ 450 mA (PN).
