FM STEREO/FM-AM TUNER
(ST-215)
Note on Ceramic Filter (CF101, 102) Replacement
and Diode D314, 315 Connection.
This set employs two ceramic filters (CF101, 102)
which should have the same color marking to identi-
fy their center frequency. Therefore FM IF offset ad-
justment by diodes (D314, 315) connection is neces-
sary
to match the center frequency of the ceramic
filters used with FM intermediate frequency.

FM intermediate
frequency is determined
by the
three types as shown
above. Ceramic filters of same
center frequency, i.e., of same color coding should be
used for CF101 and CF102.
When
replacing
the ceramic
filters, perform
the
FM Discriminator Adjustment.
