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

damaged by heat.

Flexible Circuit Board Repairing• Keep the temperature of 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.

*1 Setting the ClockThe display will flash “AM 12:00” or “0:00” when the battery is firstinserted.

1 Hold down CLOCK for more than 2 seconds.The beep sounds and the hour flashes in the display.

2 Press TUNE/TIME SET + or – until the correct hour appears inthe display.Each press changes the digit(s) by one.When you keep the button pressed, the digit(s) change rapidly.

3 Press CLOCK.The beep sounds and the minute starts to flash.Repeat step 2 to set the minute. After setting theminute, press CLOCK again. The two beeps soundand the clock starts from 0 seconds.

The clock system varies depending on the model you own.12-hour system: “AM 12:00” = midnight24-hour system: “0:00” = midnight

ELECTRICAL PARTS LIST

NOTE:• Due to standardization, replacements in the

parts list may be different from the partsspecified in the diagrams or the componentsused on the set.

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

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

• CAPACITORS:uF: µF

• RESISTORSAll resistors are in ohms.METAL: metal-film resistorMETAL OXIDE: Metal Oxide-film resistorF: nonflammable

• COILSuH: µH

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

When indicating parts by reference number,please include the board name.
