1. Safety Precaution
(This "Safety Precaution" is applied only in U.S.A.)
1. Before servicing, unplug the power cord to prevent an electric
shock.
2. When replacing parts, use only manufacturer's recommended
components for safety.
3. Check the condition of the power cord. Replace if wear or
damage is evident.
4. After servicing, be sure to restore the lead dress, insulation
barriers, insulation papers, shields, etc.
5. Before returning the serviced equipment to the customer, be sure
to make the following insulation resistance test to prevent the
customer from being exposed to a shock hazard.
- 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 jumper
AC plug and each exposed metal cabinet part, such as screw
heads, antenna, control shafts, handle brackets, etc. Equipment
with antenna terminals should read between 3M
and 5.2M
to
all exposed parts*. (Fig 1) Equipment without antenna terminals
3
should read approximately infinity to all exposed parts. (Fig 2)
*Note: Some exposed parts may be isolated from the chassis by
design. These will read infinity.
4. If the measurement is outside the specified limits, there is a
possibility of a shock hazard. The equipment should be repaired
and rechecked before it is returned to the customer.

2. Before Repair and Adjustment
Disconnect AC power, discharge Power Supply Capacitors C753 through a 10
, 5 W resistor
to ground. DO NOT SHORT-CIRCUIT DIRECTLY (with a screw driver blade, for instance), as this
may destroy solid state devices.
After repairs are completed, restore power gradually using a variac, to avoid over current.
Current consumption at AC 120 V, 60 Hz in NO SIGNAL mode should be 300~800 mA.
3. Protection Circuitry
The protection circuitry may have operated if either of the following conditions are noticed:
- No sound is heard when the power is turned on.
- 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
