Sharp GF-9090H User Manual

(Refer to Figure 32)
There are Skinds of ceramic filters (CF101, CF102)
available with this unit and they are given color indication
as tabulated below to differentiate the central frequency
from one to another among them. When using them,
be sure to make the two of the same type a pair.
When other ceramic filters than the one (red) having
the central frequency of 10.7 MHz are used, note that a
marker (10.7 MHz) of FM sweep generator, if used, will
be deviated -- therefore, adjust the generator by putting
off
the
marker.
