Please heed the points listed below during servicing and inspection.

Heed the cautions!

Spots requiring particular attention when servicing, such as

the cabinet, parts, chassis, etc., have cautions indicated on

labels or seals. Be sure to heed these cautions and the cau-

tions indicated in the handling instructions.

Caution concerning electric shock!

(1) An AC voltage is impressed on this set, so touching inter-

nal metal parts when the set is energized could cause

electric shock. Take care to avoid electric shock, by for ex-

ample using an isolating transformer and gloves when

servicing while the set is energized, unplugging the power

cord when replacing parts, etc.

(2)There are high voltage parts inside. Handle with extra care

when the set is energized.

Caution concerning disassembly and assembly!

Though great care is taken when manufacturing parts from

sheet metal, there may in some rare cases be burrs on the

edges of parts which could cause injury if fingers are moved

across them. Use gloves to protect your hands.

Only use designated parts!

The set's parts have specific safety properties (fire resis-

tance, voltage resistance, etc.). For replacement parts, be

sure to use parts which have the same properties. In particu-

lar, for the important safety parts that are marked ! on wiring

diagrams and parts lists, be sure to use the designated parts.

Be sure to mount parts and arrange the

wires as they were originally!

For safety reasons, some parts use tape, tubes or other insu-

lating materials, and some parts are mounted away from the

surface of printed circuit boards. Care is also taken with the

positions of the wires inside and clamps are used to keep

wires away from heating and high voltage parts, so be sure to

set everything back as it was originally.

Inspect for safety after servicing!

Check that all screws, parts and wires removed or discon-

nected for servicing have been put back in their original posi-

tions, inspect that no parts around the area that has been

serviced have been negatively affected, conduct an insulation

check on the external metal connectors and between the

blades of the power plug, and otherwise check that safety is

ensured.

(Insulation check procedure)

Unplug the power cord from the power outlet, disconnect the

antenna, plugs, etc., and turn the power switch on. Using a

500V insulation resistance tester, check that the insulation re-

sistance between the terminals of the power plug and the ex-

ternally exposed metal parts (antenna terminal, headphones

terminal, microphone terminal, input terminal, etc.) is 1M or

greater. If it is less, the set must be inspected and repaired.

Concerning important safety parts

Many of the electric and structural parts used in the set have

special safety properties. In most cases these properties are

difficult to distinguish by sight, and using replacement parts

with higher ratings (rated power and withstand voltage) does

not necessarily guarantee that safety performance will be pre-

served. Parts with safety properties are indicated as shown

below on the wiring diagrams and parts lists is this service

manual. Be sure to replace them with parts with the designat-

ed part number.

(1) Schematic diagrams ... Indicated by the ! mark.

(2) Parts lists ... Indicated by the ! mark.

Using parts other than the designated parts

could result in electric shock, fires or other

dangerous situations.

SAFETY PRECAUTIONS

The following check should be performed for the continued protection of the customer and service technician.

LEAKAGE CURRENT CHECK

Before returning the unit to the customer, make sure you make either (1) a leakage current check or (2) a line to chassis

resistance check. If the leakage current exceeds 0.5 milliamps, or if the resistance from chassis to either side of the power

cord is less than 460 kohms, the unit is defective.

ADJUSTMENT

Idling Current

Required measurement equipment: DC Voltmeter

1. Preparation

(1) Avoid direct blow from an air conditioner or an electric

fan, and adjust the unit at normal room temperature 15 °C

~ 30 °C (59 °F ~ 86 °F).

(2) Presetting

• POWER (Power source switch) OFF

• SPEAKER (Speaker terminal) No load

(Do not connect speaker, dummy resistor, etc.)

2. Adjustment

(1) Remove top cover and set VR501FL, VR501FR on MAIN

Unit at fully counterclockwise ( ) position.

(2) Connect DC Voltmeter to test points (FRONT-Lch:

TP501, FRONT-Rch: TP502).

(3) Connect power cord to AC Line, and turn power switch

"ON".

(4) Presetting.

MASTER VOLUME : "---" counterclockwise ( min.)

MODE : TONE DEFEAT

FUNCTION : CD

(5) Within 2 minutes after the power on, turn VR501FL clock-

wise ( ) to adjust the TEST POINT voltage to 1.5 mV

± 0.5 mV DC.

(6) After 10 minutes from the preset above, turn VR501FL to

set the voltage to 2.0 mV ± 0.5 mV DC.

(7) Adjust the Variable Resistors of other channels in the

same way.
