ADVANCED OPERATIONS
SCAN
If the Scan function is programmed, groups or channels can be scanned by
pressing the key programmed as Scan. When the Scan key is pressed, the
SCN indicator and “-SCAN-” or the revert group/ channel number appear on the
display. Scanning starts.
Scan can be used as either Single Scan or Multi Scan. Single Scan monitors
only the channels of a single group. Multi Scan monitors all channels of every
group.
When a call is received, scanning stops and the group and channel digits
appear. Press the PTT switch and speak into the microphone to respond to the
call. The transceiver will continue scanning after an adjustable time delay if the
PTT switch is released and no further signal is received.
When the displayed group is not locked out of the scanning sequence, the add
indicator (
▼ ) will appear on the display.
■ Priority Scan
The priority channel must be programmed in order for Priority Scan to
function.
The transceiver will automatically change to the priority channel when a signal
is received on it, even if a signal is being received on a normal channel.
The indicator appears when the displayed channel is the priority channel.
5-TONE SIGNALLING
5-Tone Signalling is either activated or deactivated by your dealer.
5-Tone Signalling only opens the squelch when the transceiver receives five
tones corresponding to those set up in your transceiver. When the squelch
opens, you will be able to hear the caller without any further action.
After a correct 5-Tone signal is received and the squelch opens, pressing the key
programmed as Monitor will cancel the connection.
If your dealer programmed Transpond for 5-Tone Signalling, your transceiver will
automatically send an acknowledgment signal to stations that called you with the
correct signal.
If your dealer programmed Tone Alert for 5-Tone Signalling, your transceiver will
emit a beep when the correct signal is received.
Note: This transceiver is also capable of decoding 2-Tone signals.
