4. Memory PreservationThis unit does not require memory preservation batteries. Abuilt-in memory power back-up system preserves the contentsof the memory during power failures and even when the unit isunplugged. The unit must be plugged in order to charge theback-up system.The memory preservation period after the unit has beenunplugged varies depending on climate and placement of theunit. On the average, memory contents are protected over aperiod of a few weeks after the last time the unit has beenunplugged. This period is shorter when the unit is exposed to ahighly humid climate.
2. To initialize the unitThis device employs a microprocessor to perform variousfunctions and operations. If interference generated by an external power supply, radio wave, or other electrical source results in accident which causes the specified operations and functions tooperate abnormally.To perform a result, please follow the procedure below.
1.Press and hold down the VIDEO-1 button, then press the STANDBY/ON button.2.After "clear" is displayed, the preset memory and eachmode stored in the memory, such as surround, areinitialized and will return to the factory setting.
3. Safety-check out(Only U.S.A. model)After correcting the original service problem, perform thefollowing safety check before releasing the set to the customer.Connect the insulating-resistance tester between the plug of powersupply cord and screw on the back panel.Specifications: 3.3Mohm+/-10% at 500V.
1. Replacing the fuses
This symbol located near the fuses indicates that thefuse used is fast operating type. For continued protection againstfire hazard, replace with same type fuse. For fuse rating refer tothe marking adjacent to the symbol.
Ce symbole indique que le fusible utlise est a rapide.Pour une protection permanente, n'untiliser que fusibles dememe type. Ce darnier est la qu le present symbol estappse.

5.Setting the voltage selector (Worldwide modelsonly)
Worldwide models are equipped with a voltage selector to conformwith local power supplies. Be sure to set this switch to match thevoltage of the power supply in your area before plugging in the unit.
Determine the proper voltage for your area: 220-230 V or 120 V. Ifthe preset voltage is not correct for your area, insert a screwdriverinto the groove in the switch. Slide the switch all the way to theupper (120 V) or to the lower (220-230 V), whichever is appropriate.
6.Setting the AM tuning step frequency(Worldwide models only)
You can switch the AM band tuning steps between 9 kHz and10 kHz.
The initial setting is 9 kHz. Please set the AM tuning step frequencyto match the AM band tuning step frequency in your area.
USA and Canadian models 10 kHz
Other models 9 kHz
Press MEMORY while holding down
TUNER.
Note
All the preset stations are erased when you switch the AM bandtuning steps.

ADJUSTMENT AND CONFIRMATION PROCEDURES 1 Idling current adjustment
Before Idling adjustment, turn the trimming resistors R6040,R6041,R6042,R6043 and R6044 to counter clockwise.Connect the DC voltmeter to sockets P6080,P6081,P6082,P6083 and P6084.After turn POWER to ON, adjust the trimming resistors R6040 and R6041 so that the reading of voltmeter becomes 2.5 mV. (Front channels)Adjust the trimming resistors R6042, R6043 and R6044 so that the reading of
After adjustment, attach the top cover.voltmeter becomes 1.5 mV. (Center and surround channels)
Confirm the voltage of points above after about five minutes.Front and center channelsWhen less than 7.0 mV, readjust the resistors above so that the voltage becomes 7.0 mV.When 7.0 mV to 9.0 mV, you are not necessary to adjust.When more than 9.0 mV, readjust the resistors above so that the voltage becomes 9.0 mV.Surround channelsWhen less than 4.0 mV, readjust the resistors above so that the voltage becomes 4.0 mV.When 4.0 mV to 6.0 mV, you are not necessary to adjust.When more than 6.0 mV, readjust the resistors above so that the voltage becomes 6.0 mV.Note: No load and No signal
Confirmation of protection circuit
1. Confirmation of operation of speaker relay Confirm that the speaker relays turn ON approximate. 5 seconds after the power switch is turned ON. Confirm that the speaker relays turn OFF immediately after the power switch is turned OFF.
2. Confirmation of DC detection circuit Press and hold down CD button, then press STANDBY/ON and DISPLAY buttons to set the unit to "TEST-1" mode. After "TEST-1" on the FL tube light on, press VIDEO 1 button to set the unit to "TEST-1-00". Apply DC 1.5 to 3V to DVD INPUT terminal with no load. Confirm that the speaker relay turns OFF. Apply DC -1.5 to -3V to DVD INPUT terminal with no load. Confirm that the speaker relay turns OFF. Caution: Don't apply DC voltage more than 1 sec..

ADJUSTMENT AND CONFIRMATION PROCEDURES 2 3. Confirmation of Current detection circuit Set the unit to "TEST-1-00". Connect the differentiating circuit and apply the 200Hz square signal to MULTI CHANNEL INPUT terminal of each channel. Adjust the attenuator or Volume so that the output level becomes 35V p-p. Confirm that the speaker relay does not turn OFF when a 3.0 ohm load is connected. Confirm that "Protect" indicator lights on when a 1.5 ohm load is connected. Caution:Don't continue more than 3 seconds.
