CHANGE THE SCAN LIST 

The radio can be programmed to enable the user to 
add or remove channels from the scan list. If user 
changes are enabled, follow these steps to change the 
scan list: 

1.  Turn Scan and Priority Scan off.   

2.  Select a channel to be added or removed from the 

scan list by turning the Channel Selector knob. If 
the channel is already on the scan list, 

SCN

 

appears in the display. 

3.  Press and hold the 

[SCN]

 button for more than 1 

second to toggle the channel on or off the scan list. 

GROUP SCAN  

Channels on each "Channel Scan List" in groups on 
the "Group Scan List" are scanned sequentially. The 
selected group is always scanned when Group Scan is 
enabled, even if that group is not on the Group Scan 
List. 

When Group Scan is enabled, the following features 
are disabled: 

 Priority 

Scan 

 Dual 

Priority 

Scan 

  User-Selected Channel Guard 

  Nuisance Channel Delete 

PRIORITY SCAN 

Priority Scan enables the radio to receive on any 
channel while monitoring for a message on the 
designated priority channel(s). The radio samples each 
priority channel at a preset rate (.25-2.0 seconds) 
regardless of activity on any other channel. Priority 
Scan operates only while the radio is not transmitting 
and can be used in combination with scan operation.
