4. Operation - Dealing with Interference
IF Bandwidth and Shift Adjustment (not used
in FM mode)
Once you have tuned in a signal you are going to
listen to for a while, if you hear interference from
stations on nearby frequencies, use the BANDWIDTH but-
tons and then the SHIFT and WIDTH controls to suppress
the interference. Their use varies somewhat from
mode to mode. In general, however, you will want to
press the LOCK button beneath the tuning knob before
adjusting the SHIFT and WIDTH controls, as accidentally
tetuning would invalidate your settings (particularly in
natrow-bandwidth modes). When you are ready to re-
tune to a new frequency, press LOCK again to release it,
and return the SHIFT and WIDTH controls to their default
positions (centered, and fully clockwise, respectively).
