1 Make sure that both priority and radio wide scanning are OFF (the rotating   icon is 

not indicated in the right status display).

2 Select the channel that you want to be the priority channel using the Select switch in the 

normal manner. A single beep sounds when the channel is changed (if that option is 
enabled). If the channel is in a different zone, also select the appropriate zone.

3 Press the Priority option switch and “PRIORITY” is briefly displayed to indicate that 

the selected channel is now the priority channel. Other indications that may occur are as 
follows:

- If “NO PRIORITY” is displayed, priority sampling may not be enabled on the scan 

list.

- If “SEL CHAN” is displayed, the priority channel is always the selected channel and 

cannot be changed.

- If no indication displayed, the scan list may not be user editable or the channel may 

not be in the scan list.

In additional to conventional channel scanning, a list of talkgroups can be scanned on a 
specific channel. Talkgroup scan monitors a single digital conventional channel. When a 
call is received, the radio searches the scan list for a talkgroup that matches the received 
talkgroup. Audio opens up if a match is found.

The radio can be programmed for "TalkGroup on Active Scan" scan type to return calls on 
the received talkgroup if the user talks back during scan hold time. The "TalkGroup on 
Selected Scan" scan type will always return calls on the talkgroup from the selected 
channel. 

Standard conventional calls can be placed to other radios monitoring the selected channel. 
The proper coded Call Guard squelch tone or code or P25 NAC may need to be 
transmitted by your radio for them to receive your call (see Sections 6.4 and 6.13.3).
