1. Safety precautions for AC Cord (For GS only)
2. Before Use (Caution)
Be sure to disconnect the AC cord before adjusting the voltage selector.
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. (If the power supply in your area is 110-127V or 220-
240V.)
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.)
3. Before Repair and Adjustment
Disconnect AC power, discharge Power Supply Capacitors C5815, C5818, C9513, C9533, C9534,
C9816 and C9817 through a 10
, 5W resistor to ground.
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 100/110V at 50/60 Hz & AC 240V at 50Hz in NO SIGNAL (vol. min, at
CD mode) should be ~500mA .
4. Protection Circuitry
The protection circuitry may have operated if either of the following conditions are noticed:
