SERVICE PROCEDURES
5.Setting the AM tuning step frequency
1. Replacing the fuses
(World wide models only)
This symbol located near the fuse indicates that the
fuse used is show operating type, For continued protection against
fire hazard, replace with same type fuse , For fuse rating, refer to
the marking adjest to the symbol.
Worldwide models are equipped with a switch that controls
the AM band tuning step. Please set this switch to match the
AM band tuning step frequency in your area.

2. To initialize the unit
This device employs a microprocessor to perform various
functions and operations. If interference generated by an external
power supply, radio wave, or other electrical souce results in accident
which causes the specified operations and functions to operate
abnormally.
To perform a result, please follow the procedure below.
1. Press and the hold down the VIDEO 1 button , then press the
SPEAKER A button when the nuit is Power ON.
2. After " CLEAR " is displayed, the preset memory and each mode
stored in the memory, are initialized and will return to the
factory settings.
3. Safety-check out
(Only U.S.A. model)
After correcting the original service problem perform the
following safety check before releasing the set to the customer
Connect the insulating-resistance tester between the plug of
power supply cord and terminal GND on the back panel.
Specifications: More than 10Mohm at 500V

6.Setting the voltage selector
(Worldwide models only)
World models are equipped with a voltage selector
conform with local power supplies. Be sure to set this switch to
match the voltage of the power supply in your area before
plugging in the unit.
Determine the proper voltage for your area: 230V or 120V.
If the preset voltage is not correct for your area, insert a screwdriver
into the groove in the switch. Slide the switch all the way to the right
(120V) or to the left(220V-230V), whichever is appropriate.

From soldering side
This unit does not require memory preservation batteries. A built-in
memory power back-up system preserves the contents of the
memory during power failures and even when the unit is un-plugged.
The unit must be plugged in order to charge the back-up
system.
The memory preservation period after the unit has been unplugged
varies depending on climate and placement of the unit. On the
average, memory contents are protected over a period of a few
weeks after the last time the unit has been unplugged. This pe-riod
is shorter when the unit is exposed to a highly humid cli-mate.

ADJUSTMENT PROCEDURES
IDLING CURRENT ADJUSTMENT
1. Before Idling adjustment, turn the trimming resistors R573, R574, R673, R674 and R1532 to counter clockwise.
2. Connect the DC voltmeter to sockets P511,P512, P611, P612 and P1511.
3. After turn POWER to ON, adjust the trimming resistors R573, R574, R673, R674 and R1532 so that the reading
of voltmeter becomes 2.4 to 2.6 mV.
4. After adjustment, attach the top cover.
5. Confirm the voltage of above points after five minutes.
6. When 3.1 mV to 6.4 mV : Readjust the trimming resistors above so that the voltage becomes 6.5 to 6.7 mV.
When 6.5 mV to 7.5 mV : It is not necessary to adjust.
When 7.6 mV to 13 mV : Readjust the trimming resistors above so that the voltage becomes 7.5 to 7.7 mV.

CONFIRMATION
CONFIRMATION OF PROTECTION CIRCUIT
1. Confirmation of speaker relay
Confirm that the speaker relay turns ON approximate 5 seconds after the power switch is turned ON.
Confirm that the speaker relay turns OFF immediately after the power switch is turned OFF.
2. Confirmation of DC detection circuit
1. Press and hold down CD button, then press SPEAKERS A and SPEAKERS B buttons at the same time.
2. Press DVD button, while "TEST-1_" on the FLtube is displayed.
During "TEST-1-00" on the FL tube is displayed.
3. Press SPEAKERS A button button
During "TEST-1-01" on the FL tube is displayed.
4. Apply DC 1.5 3V to MULTI CHANNEL INPUT terminals with no load.
Confirm that the speaker relay turns OFF.
5. Apply DC -1.5 3V to MULTI CHANNEL INPUT terminals with no load.
Confirm that the speaker relay turns OFF.
3. Confirmation of Current detection circuit
1. Press and hold down CD button, then press SPEAKERS A and SPEAKERS B buttons at the same time.
2. Press DVD button, while "TEST-1_" on the FLtube is displayed.
During "TEST-1-00" on the FL tube is displayed.
3. Press SPEAKERS A button button
During "TEST-1-01" on the FL tube is displayed.
4. Connect Differentiator below and apply the 50Hz square signal to the MULTI CHANNEL INPUT terminals.
5. Adjust the attenuator or Volume so that the output level becomes 35V p-p.
6. Confirm that the speaker relay does not turn OFF when a 3.0 ohm load is connected.
7. Confirm that the speaker relay turns OFF when a 1.0 ohm load is connected.
