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

automatic scanning.
Signal Stalker
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 are scanning other frequencies, turn off
normal scanning while Signal Stalker is working, or
turn off Signal Stalker and use the 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
