SERVICING NOTES

Flexible Circuit Board Repairing• Keep the temperature of the soldering iron around 270 ˚C during

repairing.• Do not touch the soldering iron on the same conductor of the

circuit board (within 3 times).• Be careful not to apply force on the conductor when soldering or

unsoldering .

Notes on chip component replacement• Never reuse a disconnected chip component.• Notice that the minus side of a tantalum capacitor may be dam-

aged by heat.

TEST MODEThis set have the test mode function. In the test mode, FM AutoScan/Stop Level and AM (MW) Auto Scan/Stop Level adjustmentscan be performed easier than it in ordinary procedure.

<Set the Test Mode>1. Set the “power select” switch (S801) is “A” position.2. Turn ON the regulated power supply. (All LEDs on the set lights

up, and the clock is displayed.)Note: Press the OFF button, if the clock is not displayed.

3. Push the preset 4 button.4. Push the preset 5 button.5. Press the preset 1 button for more than two seconds.6. Then the display indicates all lights, the test mode is set.

<Release the Test mode>1. Push the OFF button.2. Set the power select switch (S801) is “B” position.

PRECAUTION

1. Clean the following parts with a denatured-alcohol-moistenedswab:

playback head pinch rollerrubber belt capstanidlers

2. Demagnetize the playback head with a head damagnetizer.3. Do not use a magnetized screwdriver for the adjustments.4. After the adjustments, apply suitable locking compound to the

parts adjusted.5. The adjustments should be performed with the rated power sup-

ply voltage unless otherwise noted.

NOTE:• Due to standardization, replacements in the

parts list may be different from the parts speci-fied in the diagrams or the components used onthe set.

• -XX and -X mean standardized parts, so theymay have some difference from the original one.

• RESISTORSAll resistors are in ohms.METAL: Metal-film resistor.METAL OXIDE: Metal oxide-film resistor.F: nonflammable

• Items marked “*” are not stocked since theyare seldom required for routine service.Some delay should be anticipated when order-ing these items.

• SEMICONDUCTORSIn each case, u: µ, for example:uA. . : µA. . uPA. . : µPA. .uPB. . : µPB. . uPC. . : µPC. .uPD. . : µPD. .

Note on Printed Wiring Board:• X : parts extracted from the component side.• Y : parts extracted from the conductor side.• f : internal component.• : Pattern of the rear side.

Note on Schematic Diagram:• All capacitors are in µF unless otherwise noted. pF: µµF

50 WV or less are not indicated except for electrolyticsand tantalums.

• All resistors are in Ω and 1/4 W or less unless otherwise

specified.• f : internal component.• C : panel designation.• A : B+ Line.• Power voltage is dc 14.4V and fed with regulated dc power

supply from ACC and BATT cords.• Voltages are dc with respect to ground under no-signal

(detuned) conditions.no mark : FM( ) : MW/LW⟨⟨ ⟩⟩ : TAPE PLAYBACK

• Voltages are taken with a VOM (Input impedance 10 MΩ).Voltage variations may be noted due to normal produc-tion tolerances.

• Circled numbers refer to waveforms.• Signal path.

3. ELECTRICAL PARTS LISTNOTE:• Due to standardization, replacements in the

parts list may be different from the parts speci-fied in the diagrams or the components usedon the set.

• -XX and -X mean standardized parts, so theymay have some difference from the originalone.

• RESISTORSAll resistors are in ohms.METAL: Metal-film resistor.METAL OXIDE: Metal oxide-film resistor.F: nonflammable

• Items marked “*” are not stocked since theyare seldom required for routine service.Some delay should be anticipated when order-ing these items.

• SEMICONDUCTORSIn each case, u: µ, for example:uA. . : µA. . uPA. . : µPA. .uPB. . : µPB. . uPC. . : µPC. .uPD. . : µPD. .

• CAPACITORSuF: µF

• COILSuH: µH

When indicating parts by referencenumber, please include the board.
