NOTE ON SAFETY :

Symbol z Fire or electrical shock hazard. Only original parts should be used to replaced any part marked with symbol z .

Any other component substitution (other than original type), may increase risk of re or electrical shock hazard.

SHOCK, FIRE HAZARD SERVICE TEST :

CAUTION :

AC cord connector pins (with unit NOT connected to AC mains and its Power switch ON), and the face or Front Panel of product and controls and chassis bottom. Any resistance measurement less than 1 Megohms should cause unit to be repaired or corrected before AC power is applied, and veried before it is return to the user/customer.

After servicing this appliance and prior to returning to customer, measure the resistance between either primary

In case of difculties, do not hesitate to contact the Technical

Department at above mentioned address.

091105DM/DG

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.

4. DUAL BACKUP MEMORY

This product has a Dual Backup Memory function. The conventional Backup functions to memorize, in the EEPROM

(IC202) in the circuit, a current setting of the moment the main power is turned off so that it can be restored when it is turned ON again. Meanwhile, the DUAL BACKUP MEMORY is capable of memorizing any arbitrary setting that is congured while the product is in operation so as to restore it at any time. When servicing units returned from end-users for repairs, use this function to back up the current setting (e.g. Tuner Preset). This will enable the units to be returned to

the users after repairs, with the setting unchanged.

NOTE:

If end-users use this function, the data will be overwritten. The contents of the memory do not disappear even if you initialize this unit. If you want to erase, please refer to

4.2. SERVICE PRECAUTIONS

4.1. HOW TO OPERATE

-Backup-

(1) Congure a setting you would like to save in the MEMORY and hold down the "ZONE SELECT" and "DISPLAY"

buttons on the Front Panel at the same time for 3 seconds or more.

(2) The FL Display indicates "MEMORY SAVING" while the Recovery is being performed.

FLD

(3) The FL Display indicates "COMPLETE" when the Backup is completed.
