FM Polar Adjustment (East European, CIS models only)
Connection 1:
Procedure :
1. Set the modulation of FM RF SSG to AUDIO 1 kHz, 10 kHz
deviation according to “Connection 1”.
2. Tune the set to 69 MHZ.
3. Adjust the RV1702 so that the reading of frequency counter
3. Adjust the RV1702 so that the reading of frequency counter
connected to TP1702 becomes within 31.25 kHz ± 0.05 kHz.

7. Set the CT1701 to be mechanical center.
8. Adjust the L1701 so that the reading of the level meter con-
nected to TP1701 become maximum.
Then adjust the CT1701 so that the reading of the level meter
connected to TP1701 becomes maximum. (SUB CARRIER
PEAK Adjustment)
Then adjust the CT1701 so that the reading of the level meter
connected to TP1701 becomes maximum. (SUB CARRIER
