Beyond the Basics

To manually select a channel, press HOLD, enter the 
channel number and then press HOLD again.

Or, during scanning, if the radio stops at a channel 
you want to listen to, press HOLD once. (Repeatedly 
pressing HOLD at this time causes the scanner to 
step through the channels.) Press SCAN to resume 
automatic scanning.

Your scanner's Signal Stalker feature lets you set the 
scanner so it detects, then displays the frequency of 
a nearby strong radio transmission. You can set the 
scanner so Signal Stalker works "in the background" 
while you scan other frequencies, turn off normal 
scanning while Signal Stalker works, or turn off Sig-
nal Stalker and use your scanner normally. You can 
set the scanner so it alerts you when Signal Stalker 
finds a frequency. You can also set the frequency 
band where you want the scanner to look
for transmissions.

Notes: 

•

Signal Stalker works well for locating the source 
of strong local transmissions such as mobile 
and handheld two-way radios in areas with no 
other strong transmission sources. However, if 
you are in an area with many transmission 
sources (such as pager radio transmitters, multi-
use radio towers, traffic control devices, etc.),
