SIGNALLING
■ 2-Tone Signalling
Note:
◆ This transceiver is only capable of decoding 2-Tone signals. It
cannot encode a 2-Tone signal.
◆ A 2-Tone call will be cancelled if you change the channel or turn
Scan ON.
2-Tone Signalling is either activated or deactivated
by your dealer. Using this function, you will only hear
calls that are intended for you to hear.
When you receive a call with a 2-Tone signal that
matches the two tones set up in your transceiver,
squelch opens and you will hear the call.
• When a correct 2-Tone signal is received, the CALL
LED (orange) will flash and the display will alternate
between “CALL” and the current channel number (or
name).
While responding to the call by pressing the PTT
switch and speaking into the microphone, the TX
LED (red) will light, and only the channel number (or
name) will appear on the display.
• When you release the PTT switch, the LED will flash
either red or orange, and the display will either alternate
between “CALL” and the channel number (or name) or
it will only display “CALL”. This depends on how your
dealer sets up 2-Tone Signalling.
• If your dealer programmed Transpond for 2-Tone
Signalling, your transceiver will automatically send an
acknowledgment signal to the station that called you.
• If your dealer programmed Tone Alert for 2-Tone
Signalling, a tone will sound when the correct 2-Tone
signal is received.
