●
Before Adjustment
1) For dB, 1

Example : 60dB
µ
=1mV
2) 100% modulation means that the frequency deviation is
±
75kHz.
3) Install the Matching Transformer and connect FM SG.
4) Set each switch to the following position unless other-
wise specified.
INPUT SELECTOR .................. TUNER
TUNING MODE ....................... AUTO
