Conventional Mode Features
5.10 Conventional Mode Scanning
Channel scanning features common to all operating modes are described in Sections 4.9
and 4.10. The following information describes features unique to conventional operation.
5.10.1 Transmitting in Scan Mode
Each conventional scan list can be programmed for one of the following modes. These
modes determine if priority sampling occurs and also the channel on which transmissions
occur while scanning. Refer to the next section for more information on priority sampling.
No Priority - No priority channel sampling occurs when the list is selected. The radio
transmits on the selected channel.
Priority/Tx Selected - Priority sampling occurs and the priority channel or channels are
those programmed in the selected scan list. The radio transmits on the selected channel.
Priority/Tx Priority (1) - Priority sampling occurs and the priority channel or channels
are those programmed in the selected scan list. The radio transmits on the priority (1)
channel.
Priority (1) on Selected - The priority (1) channel is always the selected channel. The
radio transmits on the selected channel.
Talkback - No priority sampling occurs. The radio transmits on the channel of a call while
scanning is halted. Then once scanning resumes, it transmits on the selected channel.
5.10.2 Priority Channel Sampling
Note
The following describes priority sampling when scanning conventional channels. Priority
sampling when scanning SMARTNET/SmartZone/P25 Trunked channels is described in
Section 6.11.
The priority channel sampling feature ensures that when priority scanning, messages on
the priority channel are not missed while listening to a message on some other channel.
The radio can be programmed as just described so that the priority channel is a fixed
channel programmed in the current scan list, the currently selected channel, or not used.
Note
Priority channel sampling is not available when receiving analog encrypted (DES) calls,
nor when receiving unit calls. In addition, the priority channel is not scanned if the active
channel is an analog channel on the same frequency as the priority channel and is
programmed with CTCSS/DCS squelch control.
