During Tx, the radio will generate an emergency broadcast call on either the currently
selected channel or an FPP nominated channel.
Others may listen to the automatic transmissions to hear conversations near the radio.
Turning the radio off and on will disable emergency mode.
4.9. SCAN FUNCTIONS
The Scan 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 Colour Code for DMR). 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 the
programmed scan function button will need to be pressed. (FPP configurable).
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 (FPP
configurable, typically 3 seconds) before resuming scanning.
If a Priority Channel is assigned to Scan mode, the radio will interleave a check of this
channel between each normal Scan channel.
4.9.1. Starting a Scan
A Scan can be started by:
1. Pressing the function key that has been assigned the scan function by the FPP;
or
2. Selecting a zone channel that has been assigned to automatically scan by the
FPP; or
3. Selecting the START SCAN option under the ‘Scan’ menu.
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.
Scanning is indicated by a rotating arrow symbol.
When scanning stops on a channel, on the screen, the second line from the top shows
the name of the channel from the scan group that the radio has stopped on. If stopped
on a channel, that channel can be “skipped” by pressing the programmed skip function
