The talkgroup for a transmission is usually associated with a channel selection. A talkgroup
will address all others that have the same TGID selected.
While on a P25 Channel, the transmission will be P25 digital. For an Analogue channel, the
transmission will be Analogue FM
Note: A Transmit Limit Timer may be setup that limits a continuous transmission on a
channel. The last 10 seconds before the timer expires may be accompanied by warning
beeps.

The Scan/Vote Function allows the sequential searching of up to 16 channels if the selected
zone channel is programmed as a Scan channel, and 15 channels if the selected zone
channel is programmed as a Vote channel, for a valid signal (Carrier + CTCSS / DCS tone
for Analogue FM or Network Access Code for P25). When found, the radio will stop on that
channel until the signal disappears again.
To activate Scanning, select a channel that has been programmed as a Scan channel. Once
selected, the scanning will either start automatically, if programmed, or you will need to press
the programmed scan function button. (Field Programmer configurable).
If a selected zone channel is programmed as a Vote channel, the voting will start
automatically without any other user intervention.
While listening on the channel, the user is able to PTT on that channel. After the signal
disappears, the radio will remain listening on the channel for a short time (Field programmer
configurable, typically 3 seconds) before resuming scanning or voting
If a Priority Channel is assigned to Scan mode, the radio will interleave a check of this
channel between each normal Scan channel.

Scan can be started by
(1) Pressing the function key that has been assigned the scan function
by the Field Programmer or

enabled in the FPP, starts voting.
The top line of the display still shows the name of the current selected channel. The second
line of the display shows the name of the current selected zone while scanning/voting.
The Channel can be changed by using the
and
keys. Other channels may be either
Scan or Normal channels, depending on the radio’s configuration.
