If you feel uncomfortable the break, set the Signal Stalker voice interrupt to off. The scanner doesn't check the 
Signal Stalker during receiving the audio, so the audio is not interrupted. The scanner resumes checking the 
Signal Stalker when the signal ends. 
 
 
 
 

 
The scanner tracks transmissions that use the Motorola Type I, Type II, hybrid,   
and EDACS and LTR analog trunking systems. The frequencies for many of the 800 MHz,   
900 MHz, and EDACS and LTR public safety systems are listed in the separate   
National Public Safety Trunked System Frequency Guide included with your scanner. 
 

 
SETTING THE SCANNER TO THE TRUNKING MODE 

 
The scanner allows you to track up to 10 systems at a time. You can trunk scan or search and scan 
conventional frequencies at the same time. You can also program conventional frequencies in the same bank 
as trunking systems. 
 
After the scanner is finished checking activity in the trunked system,  it scans other  conventional frequencies 
in the bank. (Only trunking frequencies are programmed in trunk mode.) 
 
If a system is inactive for 1 second and there are no conventional channels in the bank, the scanner starts 
scanning the next selected trunk bank.    If you turned 

DELAY 

on, the scanner starts scanning the next trunk 

bank after about 2 seconds. 
 
To scan both trunking and conventional banks, select the banks you wish to be active with trunking off, then 
press 

. The scanner begins scanning. To return to conventional scanning, press 

TRUNK 

again. 

 
SETTING SQUELCH FOR THE TRUNKING MODE

 

 
For trunked reception, a good squelch setting is in the center of the range with the white marker pointing up. If it 
is set too high, it could prevent your scanner from locking on the control channel reliably. If it is set too low, it will 
slightly delay finding the control channel. The best setting is the same as for conventional reception and is 
critical for monitoring trunked systems.

  

 
PROGRAMMING TRUNKED FREQUENCIES 

 
Follow these steps to select, program, and store trunked frequencies. 
 

1.  If you are not in conventional programming mode, press 

beforehand

. Press 

. Your 

scanner beeps a tone. Then 

 

appears and one or more bank numbers flash. 

 

2.    Press the number key (

-9

 and 

) of the desired target storage bank.   

Select one of the trunk systems by repeatedly pressing 

 

or 

  to select a trunking system type, 

then press 

 

.  

 

 You can select from the following six systems:
