Dtmf Signalling; Dbd (Dead Beat Disable) - Kenwood TK-780 series Instruction Manual

DTMF SIGNALLING

Your dealer can program a group or channel with DTMF signalling. When you
receive a call with a code that matches yours, the signalling indicator ( ) will
flash and a tone will sound. Squelch opens and you will hear the call.
Squelch will close when you receive a call with a code that matches your
signalling reset code.
When making a call on a group or channel programmed with a DTMF signalling
code, the signalling indicator will light and the squelch will open.
If your dealer programmed Transpond for DTMF signalling, your transceiver will
automatically send an acknowledgment signal to the station that called you with
the correct DTMF code.

DBD (DEAD BEAT DISABLE)

Depending on how your dealer programs your transceiver, when you receive a
call containing a DBD code, either transmit mode or receive and transmit modes
will be disabled. When a DBD code is received, a tone will sound.
DBD is cancelled when you receive a call with a DBD cancel code.
