Precautions in Repairing
Note :

As a FM front end (U1) is difficult to repair if faulty, replace

it with new one.

(FM is no adjustment)

[AM]

BAND : AM
Signal generator

Adjustment Location : MAIN board (Component side)

0 dB = 1 µV

• Repeat the procedures in each adjustment several times for the

maximum level meter indication.

• The frequency coverage and tracking adjustments should be finally

done by the trimmer capacitors.

AM IF ADJUSTMENT

Adjust for a maximum reading on level meter.

CFT1

450kHz

AM TRACKING ADJUSTMENT

Adjust for a maximum reading on level meter.

612kHz

CT1

1,404kHz

AM FREQUENCY COVERAGE ADJUSTMENT
