PB Head Azimuth Adjustment
Procedure:
1. Put the set into the FWD PB mode.
2. Turn the screw and check the output peak value.  Adjust the
screw so that the peak value in channels L and R coincides
within 2 dB.
3. Check the phase in the FWD PB mode.
4. Repeat the above adjustment for the REV PB mode.
5. Check that output level difference between FWD PB mode
and REV PB mode is within 4 dB.

Cautions during repair
When the tuner unit is defective, replace it by a new one be-
cause its internal block is difficult to repair.
Note:
Adjust the tuner section in the sequence shown below.
1. FM Auto Seek/Stop Level Adjustment
2. FM Stereo Separation Adjustment
3. FM RDS S-Meter Adjustment
4. MW Auto Seek/Stop Level Adjustment
FM Auto Seek/Stop Level Adjustment
Setting:
[TUNER]
