Option Signalling (Dtmf/2-Tone); Audible User Feedback Tones; Dead Beat Disable; And/Or - Kenwood 762G Service Manual

Off hook decode
If the Off hook decode function has been enabled, re-
moving and replacing the microphone on the hook has no
effect for decoding QT/DQT and option signalling.
"TOT" pre-alert
The transceiver has "TOT pre-alert timer. This parameter
selects the time at which the transceiver generates "TOT"
pre-alert tone before "TOT" is expired.
"TOT" will be expired when the selected time passes
from a TOT pre-alert tone.
"TOT" re-key time
The transceiver has "TOT" re-key timer. This timer is the
time you can not transmit after "TOT" exceeded. After "TOT"
re-key time expired you can transmit again.
"TOT" reset time
The transceiver has "TOT" reset timer. This timer is the
minimum wait time allowed during a transmission that will
reset the "TOT" count.
"TOT" reset time causes the "TOT" to continue even after
PTT is released unless the "TOT" reset timer has expired.
OST (Operator Selectable Tone)
(TK-760G K market models only)
The transceiver is capable to have "OST" function and 16
tone pair (QT/DQT).
Clear to transpond
The transceiver waits the transpond of 2-tone /DTMF if
channel is busy until channel open. This feature prevents
the interference to other party.

6. Option Signalling (DTMF/2-Tone)

Built-in DTMF decoder is available for option signalling.
Built-in 2-tone decoder is available for option signalling.
It is possible to use individual call, group call, D.B.D.
(Dead Beat Disable). D.B.D. is used with DTMF only.
If the option signalling matches, a predetermined action
will occur.
If option signalling matches on a group/channel which is
set up with option signalling, the option signalling indicator
(CALL) will flash and option signalling will be released. The
transpond or alert tone will sound.
The orange LED will flash.
While option signalling matches (or if option signalling is
deactivated when you are transmitting), you can mute or
unmute QT/DQT/Carrier.
