Voice interrupt note:

While the Signal Stalker I is on and the 
scanner is receiving an audio signal (voice) 
in normal scanning, the scanner checks the 
Signal Stalker I every 2 seconds causing the 
audio signal to break at that moment. 

3: Logging

Set this function to 

1: On

 to scan log channels 

along with normal channels. Set this function 
to

2: Off

 if you do not want to scan log 

channels.

Logging notes:

•

When the scanner finds a strong signal, it 
automatically saves the signal to one of 10 log 
channels. If the scanner finds a new frequency 

after the 10 log channels are fully stored with 
frequencies, the oldest memory is deleted and 
the new frequency is stored in that channel. 
You can scan the log channels along with the 
normal 1000 channels.

•

The 10 log channels are located after Channel 
999. You can access them by selecting S-00 to 
S-09 or by manually entering channel numbers 
1000 to 1009.

•

You cannot program frequencies in the log 
channels.

•

You can lock out the log channels like normal 
channels.

•

The scanner stores signals found by the Signal 
Stalker I even if the logging function is off. The 
frequencies in the log channels are deleted 
when the scanner is turned off.

1: On 

if you want the
