18 5-Tone Signaling
5-Tone Signaling
5-tone (also known as multi-tone) signaling is selec-
tive calling that segregates a group of users from
others on a channel, using a set of audible tones.
Each radio has a unique identity and you can direct
calls to individuals within your own group and
make different types of calls. An emergency call
may also be programmed.
Receiving a
5-Tone Call
When a call is received that contains your radio’s
identity, the radio gives a ringing tone and the call
LED flashes.
Note: Your radio may be programmed to
display the caller’s identity when a call is
received. This can be either a name or a
number. Contact your system manager or the per-
son who programmed your radio for more informa-
tion.
To accept the call, press the PTT key and begin
speaking.
Clearing a Call
If you do not wish to answer the call, press any of
the control head keys to cancel the ringing tone and
clear the call. The function associated with the key
you press will not be invoked.
