Note on Ceramic Filter (CF1, 2) Replacement.

should have the same color marking to identify their center
frequency. Therefore FM IF offset adjustment by patem
bridged is necessary to match the center frequency of the
ceramic filters used with FM intermediate frequency.

types as shown above, Ceramic filters of same center

CF 1, CFZ.

When replacing the ceramic filters, perform the FM
