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 ﬁ re or electrical shock hazard.

安全上の注意：

zがついている部品は、安全上重要な部品です。必ず指定されている部品番号の部品を使用して下さい。

SHOCK, FIRE HAZARD SERVICE TEST :

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

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 veriﬁ ed before it is return to the user/customer. Ref. UL Standard No. 60065.

In case of difﬁ culties, do not hesitate to contact the Technical Department at above mentioned address.

091105DM/DG

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. Be sure to test for leakage current with the AC plug in both polarities, in addition, in each power ON, OFF and STANDBY mode, if applicable.

CAUTION

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. be sure to heed these causions and the cautions indicated in the handling instructions.

◎Caution concerning electric shock!

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

internal metal parts when the set is energized could cause electric shock. Take care to avoid electric shock, by for example using an isolating transformer and gloves when servicing while the set is energized, unplugging the power cord when replacing parts, etc.

(2) Tere 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 manufacturing parts from sheet metal, there may in some rare cases be burrs on the edges of parts which could cause injury if ﬁ ngers are moved across them. Use gloves to protect your hands.

◎Only use designated parts!

The set's parts have specific safety properties (fire resistance, voltage resistance, etc.). For replacement parts, be sure to use parts which have the same poroperties. In particular, for the important safety parts that are marked z 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 seasons, some parts use tape, 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 wores omsode amd 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 disconnected for servicing have been put back in their original positions, inspect that no parts around the area that has been serviced have been negatively affected, conduct an inslation 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 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 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 poreserved. 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 designated part number.

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

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

Using parts other than the designated parts could result in electric shock, ﬁ res or other dangerous situations.

NOTE FOR SCHEMATIC DIAGRAM

WARNING:

Parts marked with this symbol z have critical characteristics. Use ONLY replacement parts recommended by the manufacture

CAUTION:

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.

WARNING:

DO NOT return the unit to the customer until the problem is located and corrected.

Warning indication by the POWER LED

If the power is turned off when a protection incident has been detected, the POWER LED (red) ﬂ ashes as a warning according to the conditions in which the protection incident occurred.

(1) ASO/DC PROTECTION : Flashes in cycles of 0.5 seconds (0.25 seconds lit, 0.25 seconds off) (2) THERMAL PROTECTION : Flashes in cycles of 2 seconds (1 second lit, 1 second off)

3. DUAL BACKUP MEMORY

This product has a Dual Backup Memory function. The conventional Backup functions to memorize, in the EEPROM (U5302) 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 conﬁ 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 3.2. SERVICE PRECAUTIONS.

3.1. HOW TO OPERATE

-Backup-

(1) Conﬁ gure a setting you would like to save in the MEMORY and hold down the "BAND" and "ENTER" buttons on the

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

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

FLD

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

FLD

-Recovery-

(1) Hold down the "BAND" and "MENU" buttons at the same time for 3 seconds or more. (2) The FL Display indicates "MEMORY LOAD" while the Recovery is being performed.

FLD

(3) After the FL Display indicates "COMPLETE", the product goes into Standby mode. When the power is restored, the

Recovery is completed.

FLD

The FL Display indicates "NO BACKUP" if the DUAL BACKUP MEMORY has not been activated with no data to be recovered saved in the Memory.

3.2. SERVICE PRECAUTIONS

When the Flash Rom (U5302) on the HDMI PWB is replaced make sure, in order to maintain consistency with the Backup Memory, to clear the DUAL BACKUP MEMORY in thefollowing way :

-How to clear the Backup Memory-

(1) Hold down the "BAND" and "AUTO" buttons at the same time for 3 seconds or more. (2) The FL Display indicates "BACKUP CLEAR" while the memory is being cleared.
