knob.
Pressing the
[
NAR
]
button once more returns the band-
width control to the WITDH/SHIFT system. The factory

ADVICE:
 When the narrow bandwidth is selected, the “ ”
icon will appear in the display.
 Even if the
[
NAR
]
button has been pressed to engage
the narrow filter, you may adjust the narrow IF band-
width by rotating the
[
SELECT
(
WIDTH
)]
knob (re-
quires pressing the
[
WIDTH
]
button). The IF SHIFT
still is operational (requires pressing the
[
SHIFT
]
but-
ton). For many applications, you may find that simply
pressing the
[
NAR
]
button instead of adjustment of
the
[
SELECT
(
WIDTH
)]
knob, may be satisfactory for
interference reduction.
 When you press the
[
NAR
]
button in the FM mode,
both transmit and receive bandwidths are narrowed.
