Pressing the NAR switch once more returns the bandwidth control to theWidth/Shift system. The factory default bandwidths are:SSB ModePressing the NAR switch selects a bandwidth of 1.8 kHz.CW/RTTY/PKT ModesPressing the NAR switch selects a bandwidth of 300 Hz.AM ModePressing the NAR switch selects a bandwidth of 6 kHz.FM Mode (28/50 MHz Bands)Pressing the NAR switch selects a bandwidth of 9 kHz.Advice The bandwidth applied when the NAR switch ispressed may be adjusted using the Menu.

For manyapplications, you may find that simple adjustment ofthe Width control, instead of engaging the Narrowfilter, may be satisfactory for interference reduction. When you press the NAR button in the FM mode,both the transmit and receive bandwidths are narrowed.NoteWhen the NAR button is pressed, the WIDTH con-trol no longer functions.
