QUICK REFERENCE GUIDE

O

ne optional filter can be installed in the IC-703. 

Narrow filters help reject interference from adjacent
signals and obtain good selectivity. 

Wide filters provide improved audio for SSB opera-
tion when no interfering signals are present.

Narrow filters for AM/FM modes are standard.

FILTER PRESETTING:
After you install a filter (see p. 87 for installation), you
must specify the installed filter in initial set mode (item
