signal then a defined emergency procedure is activated.
CTCSS/CDCSS
If CTCSS/CDCSS is set on the current channel, causes a CTCSS/CDCSS match to be
required on an incoming signal for radio to unmute. Radios that set with the same
CTCSS/CDCSS, or no CTCSS/CDCSS, can receive from you.
Your dealer may program the current channel with CTCSS/CDCSS, to prevent unwanted
conversations on the same frequency.
The radio will not unmute to an incoming call that with invalid CTCSS/CDCSS. This
feature does not mean that your conversation will not be heard by others.
DTMF
The DTMF signalling can be enabled/disabled by your dealer. If DTMF signalling is set on
the current channel, press the programmed Call 1/Call 2 key to transmit DTMF code.
