Scan; Priority Scan; 2-Tone Signalling - Kenwood TK-780 Instruction Manual

SCAN

If the Scan function is programmed, groups or channels can be scanned by
pressing the key programmed as Scan. 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 the Scan key is pressed, the
SCN indicator and "-SCAN-" or the revert group/ channel number, appear on the
display and scanning starts.
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.

2-TONE SIGNALLING

2-Tone Signalling is either activated or deactivated by your dealer.
2-Tone Signalling only opens the squelch when the transceiver receives two
tones corresponding to those set up in the transceiver. When the squelch opens,
you will be able to hear the caller without any further action.
After a correct 2-Tone signal is received and the squelch opens, pressing the key
programmed as Monitor will cancel the connection.
If your dealer programmed Transpond for 2-Tone Signalling, your transceiver will
automatically send an acknowledgment signal to the station that called you with
a correct 2-Tone signal. Transpond does not function when you are called as a
Group call.
If your dealer programmed Tone Alert for 2-Tone Signalling, your transceiver will
emit a beep when the correct 2-Tone signal is received.
Note: This transceiver is only capable of decoding 2-Tone Signals. It cannot encode a 2-Tone Signal.
