DOptional filter selection

Two optional filters can be installed in the IC- 706MKIIG.

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.

Consult the table below to select a filter most suitable for your operating needs.

Narrow filters for AM/FM modes are standard.

FILTER PRESETTING:

After you install a filter (see p. 60 for installation), you must specify the installed filter in initial set mode (item 19 “OPT. FIL 1” or item 20 “OPT. FIL 2”; see p. 51).

FILTER ON/OFF:

➀Select M3.

•Push [DISPLAY] 1 or 2 times if G or S appears.

•Push [MENU] one or more times to select M3.

➁Push [(F-1)FIL] momentarily to select the narrow filter; for 2 sec. to select the wide filter.

•ã appears when the narrow filter is selected; ç appears when the wide filter is selected.

Note: When selecting the narrow filter, the graphic passband is narrowed (see diagram below).
