FM ADJUSTMENT
Modulation M:MONO MOD., 400Hz 30%(22.5kHz Dev.) or 400Hz 100%(75kHz Dev.)
S1:STEREO MOD., 1kHz, L or R=30%(20.25kHz+7.5kHz Dev.)
S2:STEREO MOD., 1kHz, L or R=60%(40.5kHz+7.5kHz Dev.)
NOTE:Before proceeding to further adjustments after switching power ON, let the tuner run for ten minutes to allow
the circuits to stabilize.
