I BEFORE REPAIR AND ADJUSTMENT

Disconnect AC power, Discharge both Power Supply Capacitors C701 ~C704 through a 109, SW resistor to ground.
DO NOT SHORT-CIRCUIT DIRECTLY (with a screwdrive blade, tor instance), as this may distroy solid state

devices.

After repairs are completed, restore power gradually using a variac, to avoid overcurrent.

Current consumption at 50Hzl60 Hz in N0 SIGNAL mode should be shown below with respect to supply voltage

230VI240VI110-127VI220-240V.

Power supply voltage AC 230V AC 240V (AcA1C1 0159929 V) (AG/"2202 i021:0 V)
50HZ 12~60mA 50 Hz 12~60 mA 50 Hz 20~100n1A 50 Hz 12~60mA
