Receiving a two-tone call
Two-tone signaling is used to call either individual or groups of
radios. When your radio receives a two-tone call that it can
decode, it beeps, indicating which type of two-tone call has been
received.
■
One long beep: a two-tone individual call has been received.
■
Two medium beeps: a two-tone group call has been received.
■
Three short beeps: a two-tone super group call has been
received. A super-group call is addressed to all radios in the
fleet.
To accept the call, press the PTT key and begin speaking.
Overriding two-tone signaling
The two-tone override function allows you to override two-tone
signaling on your current channel. When you activate two-tone
override, the radio’s mute opens and you can hear all two-tone
calls on the channel.
To turn two-tone override on or off:
■
Press the assigned function key.
While two-tone override is on, the LED slowly flashes green.
