Mi SAFETY PRECAUTION (this "safety precaution" is applied only in U.S.A.)
. Before servicing, unplug the power cord to prevent an electric shock. . When replacing parts, use only manufacturer's recommended components for safety.
. Check the condition of the power cord. Replace if wear or damage is evident. . After servicing, be sure to restore the lead dress, insulation barriers, insulation papers, shields, etc. a. Ah BeR foOreD returning the serviced equipment to the customer, be sure to make the following insulation
test to prevent the customer from being exposed to a shock hazard.
resistance
¢ INSULATION RESISTANCE TEST
1. Unplug the power cord and short the two prongs of the plug with a jumper wire. 2. Turn on the power switch. 3. Measure the resistance value with ohmmeter between the jumpered AC plug and each exposed metal cabinet
part, such as screwheads, antenna control shafts, handle brackets, etc. Equipment with antenna terminals should read between 3MQ and 5.2MQ to all exposed parts. (Fig. A) Equipment without antenna terminals should read approximately infinity to all exposed parts. (Fig. B)
Note: Some exposed parts may be isolated from the chassis by design. These will read infinity.

Resistance=Approx. oo
4. If the measurement is outside the specified limits, there is a possibilty of a shock hazard. should be repaired and rechecked before it is returned to the customer.
Mi PROTECTION CIRCUITRY
The equipment
The protection circuitry may have operated if either of the following conditions is noticed: ¢ No sound is heard when the power is turned on. ¢ Sound stops during a performance. The function of this circuitry is to prevent circuitry damage if, for example, the positive and negative speaker connection wires are " shorted", or if speaker systems with an impedance less than the indicated rated impedance of the amplifier are used.
If this occurs, follow the procedure outlines below: 1. Turn off the power. 2. Determine the cause of the problem and correct it. 3. Turn on the power once again after one minute.
Note: When the protection circuitry functions, the unit will not operate unless the power is first turned off and then on again.
Mi BEFORE REPAIR AND ADJUSTMENT
Disconnect AC power, Discharge both Power Supply Capacitors C703 and C704 (80V 1200uUF), C705 and C706 (63V 2200u1F) through a 100, 5W resistor to ground. DO NOT SHORT-CIRCUIT DIRECTLY (with a screwdrive 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 120V, 60Hz in NO SIGNAL mode should be 410~810mA.
