Frequency Search
To manually search through the frequency range of any of the bands (AM, FM or Aviation), the Up
button or Down button may be pressed at any time to select the next higher or lower frequency.
This uses 10 kHz steps in the AM frequency range, 100 kHz steps in the FM frequency range and
25 kHz steps in the Aviation frequency range. The
Up and Down buttons may be pressed repeatedly
to continue changing the selected frequency.
To automatically search the entire frequency range of the current band for a broadcasting signal,
the
Up button or Down button may be pressed and held for two seconds. The screen will flash
SCAN as seen below.
The frequencies will either scroll up or down depending upon whether the Up or Down button was
used to initiate the search.
When a broadcasting signal is found, the Air Scan
®
will stop temporarily on that frequency. When
the end of the frequency range is reached during an upward search, the search automatically
continues searching at the beginning of the frequency range. Likewise, when the beginning of the
frequency range is reached during a downward search, the search automatically continues at the
end of the frequency range.
Once you have located your desired frequency, press the STOP button to cancel the search.
NOTE: On the Aviation band search functions differently. The Air
Scan will not continue to search if a frequency is active. It
is very important that the squelch be properly adjusted
prior to initiating a search. The background static received
with the squelch off may be strong enough to disrupt a
search. If a search gets "stuck" on a frequency with too
much background noise, increase the squelch or press the
Up or Down button to skip that frequency and resume
searching.
