OPTIONAL SIGNALING
Your dealer may also program several types of optional
signaling for your transceiver channels.
■
5-tone Signaling:
This function opens the squelch only when the transceiver
receives the 5 tones programmed in your transceiver, in
succession. Transceivers that do not transmit the correct
tones will not be heard.
■ DTMF Signaling:
This function opens the squelch only when the transceiver
receives the DTMF code (3 to 0 digits) programmed in your
transceiver. Each transceiver is normally programmed with
a unique code. You will not hear calls from transceivers that
are not programmed with a matching code.
■ FleetSync Signaling:
FleetSync is a protocol owned by Kenwood Corporation.
This function opens the squelch only when the transceiver
receives the Fleet code and ID code programmed in your
transceiver. Calls that do not contain the correct codes will
not be heard.
BEGINNING/ END OF TRANSMISSION SIGNAL
The Beginning/ End of Transmission identification signals are
used to access some repeaters and telephone systems. The
Beginning of Transmission ID signal is transmitted when you
press the PTT switch and the End of Transmission ID signal is
transmitted when you release the PTT switch.
