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.

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.

When started up, the error information is displayed.
Starting up:
●All model commonness
With the "STATUS" and "MENU" buttons pressed, press the "ON/STANDBY" button to turn the power on. The error
(protection history display) mode is set.
Now, press the "STATUS" button to turn on the FL display.
2.2. About the display on the FL display
When the "STATUS" button is pressed after setting the error (protection history display) mode, a history like the one
shown below is displayed, depending on the conditions.
(1) Normally (when there has been no protection incident)

Cause: The line between speaker terminals is shorted, or use speakers having impedance less than that specifi ed.
Supplementary information: As the excess current is detected after operation of the speaker relay, the shorted
Turning on the power without correcting the abnormality will cause the protection function to work about 5 seconds
later and the power supply will be shut off.
(3) For DC (when the last protection incident was DC protection)
Upper

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 2.2. 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 "SLEEP" 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 "SLEEP" 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.
