USING PRIORITY
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.
1. Press
PGM, then press PRI/ALERT.

2. Enter the frequency you want to enter into the priority channel, then press
ENT. The display
flashes twice.
To turn on the priority feature, press
PRI/ALERT during scanning or searching.

AVOIDING IMAGE FREQUENCIES
You might discover one of your regular stations on another frequency that is not listed. It might be
what is known as an image frequency. For example, you might find a service that regularly uses a
frequency of 453.275 also on 474.675 MHz.
To see if it is an image, do a little math.
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
