Note 1:As a front-end (FE1) is difficult to repair if faulty, replace
it with new one.
Note 2:No adjustment is needed due to a tuner pack for except

Procedure:Adjustment Location
1. Set the output of SSG so that the input level of the set becomes[TCB BOARD] (Component Side)
55 dB.
2. Tune the set to 999 kHz or 1,050 kHz.
3. Adjust RV41 to the point (moment) when the TUNED indicatorTM1
will change from going off to going on.
