SAFETY PRECAUTIONS

The following items should be checked for continued protection of the customer and the service technician.

LEAKAGE CURRENT CHECK

Before returning the set to the customer, be sure to carry out 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 set is defective. Be sure to test for leakage current with the AC plug in both polarities, in addition, when the set's power is in each state (on, off and standby mode), if applicable.

CAUTION

Please heed the following cautions and instructions during servicing and

inspection.

◎Heed the cautions!

Cautions which are delicate in particular for servicing

are labeled on the cabinets, the parts and the chassis, etc. Be sure to heed these cautions and the cautions

described in the handling instructions.

◎Cautions concerning electric shock!

(1) An AC voltage is impressed on this set, so if

you touch internal metal parts when the set is

energized, you may get an electric shock. Avoid getting an electric shock, by using an isolating

transformer and wearing gloves when servicing

while the set is energized, or by unplugging the power cord when replacing parts, for example.

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

extra care when the set is energized.

◎ Caution concerning disassembly and

assembly!

Through great care is taken when parts were manufactured from sheet metal, there may be burrs on the edges of parts. The burrs could cause injury if ngers are moved across them in some rare cases.

Wear gloves to protect your hands.

◎Use only designated parts!

The set's parts have specic safety properties (re resistance, voltage resistance, etc.). Be sure to use

parts which have the same properties for replacement.

The burrs have the same properties. In particular, for

the important safety parts that are indicated by the z

mark on schematic diagrams and parts lists, be sure to

use the designated parts.

◎ Be sure to mount parts and arrange the wires

as they were originally placed!

For safety seasons, some parts use tapes, tubes or other insulating materials, and some parts are mounted

away from the surface of printed circuit boards.

Care is also taken with the positions of the wires by arranging them and using clamps to keep them away from heating and high voltage parts, so be sure to set everything back as it was originally placed.

◎Make a safety check after servicing!

Check that all screws, parts and wires removed or disconnected when servicing have been put back in their original positions, check that no serviced parts have deteriorate the area around. Then make 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 on the power. Using a 500V insulation resistance tester, check that

the insulation resistance value between the inplug and

the externally exposed metal parts (antenna terminal, headphones terminal, input terminal, etc.) is 1MΩ or greater. If it is less, the set must be inspected and

repaired.

CAUTION

Concerning important safety

parts

Many of the electric and the structural parts used in the set have special safety properties. In most cases

these properties are difcult to distinguish by sight, and the use of replacement parts with higher ratings (rated power and withstand voltage) does not necessarily

guarantee that safety performance will be preserved. Parts with safety properties are indicated as shown below on the wiring diagrams and the parts list in this

service manual. Be sure to replace them with the parts

which have the designated part number.

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

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

The use of parts other than the

designated parts could cause electric

shocks, res or other dangerous

situations.

NOTE FOR SCHEMATIC DIAGRAM

NOTE FOR PARTS LIST

WARNING:

Parts indicated by the z mark have critical characteristics. Use ONLY replacement parts recommended by the manufacturer.

CAUTION:

WARNING:

DO NOT return the set to the customer unless the problem is identied and remedied.

NOTICE:

ALL RESISTANCE VALUES IN OHM. k=1,000 OHM / M=1,000,000 OHM ALL CAPACITANCE VALUES ARE EXPRESSED IN MICRO FARAD, UNLESS OTHERWISE INDICATED. P INDICATES MICRO-MICRO FARAD.

NOTE FOR PARTS LIST

Parts indicated by "nsp" on this table cannot be supplied.

When ordering a part, make a clear distinction between "1" and "I" (i) to avoid mis-supplying.

A part ordered without specifying its part number can not be supplied.

After completion of the updating operation, the new version number can conrmed by starting up the AVR-1312 according

to the following procedure.

With the following operation, the AVR-1312 can be set to the Flash ROM Version-Number Conrmation mode.

Turn on power switch while simultaneously pressing "DIMMER" and "STATUS" buttons on the front panel. Every time the "STATUS" button is pressed, version number of the Model, Main, DSP, … are indicated on the front panel section. (Refer to "1.2. Display other" (page 14 ))

Adjusting Idling Current

Required measurement equipment: DC Voltmeter

1. Preparation

(1) Avoid direct blow from an air conditioner or an electric fan and humidity should be moderate, and place the set at

normal usage environment.

Temperature should be at 15 °C ~ 30 °C.

(2) Presetting

• POWER (Power source switch) OFF

• SPEAKER (Speaker terminal) No load

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

2. Adjustment

(1) Removed the top cover and set VR41(FL),VR45(FR),VR42(C),VR44(SL),VR43(SR), on Main Amp. Unit at fully

counterclockwise position.

(2) Connect DC Voltmeter to test points (Front-Lch:CN51,Front-Rch:CN55,CENTERch:CN53,

Surround-Lch:CN52,Surround-Rch:CN54).

(3) Connect the power cord to AC Line, and set the power switch to "ON".

(4) Presetting.

MASTER VOLUME : "---" counterclockwise (c min.) SPEAKER (Speaker terminal) : No load

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

FUNCTION : DVD

(5) Within 2 minutes after the power on, turn VR41 clockwise (x) to adjust the TEST POINT voltage at

1.5 mV ± 0.5 mV DC.

(6) After 10 minutes from the preset above, turn VR41 to set the voltage to 2.0 mV ± 0.5 mV DC.

(7) Adjust the Variable Resisters of each channel (VR42-VR45) in the same way.
