Conventional Features
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.
6.10.4 Talkgroup Scanning
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.
6.11 Standard Conventional Calls
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).
