Spectrum Sweeper

Your scanner's Spectrum Sweeper feature provides a powerful new tool for
you to rapidly detect, monitor and store frequencies for nearby radio transmis-
sions. The Spectrum Sweeper feature is similar in functionality to portable fre-
quency counters that cost much more than your scanner, but provides many
advantages over typical portable frequency counters. For example:
The Spectrum Sweeper allows you to sweep the entire range of your scanner's
design frequencies, or you can specify those frequency ranges that you wish
to sweep and exclude ranges that you do not want to sweep. This allows you to
omit frequency ranges with constant strong frequency activity, such as those
with paging or broadcast transmitters. Many portable frequency counters will
remain locked to a nearby constant signal, such as a paging or broadcast
transmitter, and will not function properly until you have left the vicinity of the
transmitter.
The Spectrum Sweeper feature is more sensitive than portable frequency
counters and will detect transmissions at a greater distance.
Once an active frequency is found, the transmission is played through your
scanner's speaker, and you can quickly store it in any of your scanner's memory
locations.

Using Spectrum Sweeper

The Spectrum Sweeper can be set to watch for activity on all band, Police/Fire,
Aircraft, or Ham frequencies. When the scanner is in manual, scan or tune
mode, press to watch for activity on all band. When the scanner is in Police/
Fire search band, press to watch for activity on Police/Fire band. When the
scanner is in Aircraft band, press to watch for activity on Aircraft band.
When the scanner is in Ham band, press to watch for activity on Ham band.
You can also turn on/off frequency sub-bands using the corresponding num-
ber keys while Spectrum Sweeper is active.
Note: Priority mode is not available while using the Spectrum Sweeper.
