The priority feature lets you scan through channels and still
not miss important or interesting calls on a frequency you
select. You can program one frequency into the priority
channel. As the scanner scans, if the priority feature is
turned on, the scanner checks the priority channel for
activity every 2 seconds.

You might hear one of your regular stations on another
frequency that is not listed. For example, you might find a
service that regularly uses a frequency of 453.275 also on
474.675 MHz. Do the following to determine if you are
listening to an image frequency:

Note the new frequency

474.675

Double the intermediate frequency of 10.7 MHz

(21.400)

and subtract it from the new frequency

–21.400

If the answer is the regular frequency

453.275

then you have tuned to an image.
