■
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.
OPERATING FEATURES
■
AND/OR
You can select AND or OR for option signalling match
conditions.
Alert/Transpond
AND
QT/DQT+DTMF (2-tone); Option matches = Action
OR
QT/DQT+DTMF (2-tone); Option matches = Action
AF mute open
AND
QT/DQT+DTMF (2-tone); Option matches = Action
OR
QT/DQT/ID; Signalling only matches = Action
With OR set up, alert/transpond will not function with
only DTMF.
With OR set up, AF mute will not release when only
DTMF matches.
With a conventional channel not set up with QT or DQT,
only the carrier is considered when signalling matches.
■
Auto Reset
If option signalling matches a group set up with option
signalling, option signalling is released. After matching op-
tion signalling, option signalling will temporarily reset auto-
matically.
■
Dead Beat Disable
If the D.B.D. code matches, a predetermined action will
occur. Whether option signalling is activated or not, when
D.B.D. matches on any channel, the transceiver will become
TX inhibited or TX/RX inhibited. While D.B.D. is active, if the
D.B.D. code + "#" code is received, D.B.D. will disactivate.
When D.B.D. matches, transpond will function. Alert will
not be output, and option signalling match icon will not ap-
pear.
7. Audible User Feedback Tones
The transceiver outputs various combinations of tones to
notify the user of the transceiver operating state. The main
tones are listed below.
The high tone is 1477Hz, the mid tone is 941Hz, and the
low tone is 770Hz.
■
Power on tone
This tone is output when the transceiver is turned on.
(The high tone is output for 500ms.)
■
Alert tone
This tone is output when the transceiver is TX inhibition
for TOT, and PLL unlocked. It is output until the PTT button
is released.
■
DBD on tone
When a D.B.D. code is received, transpond tone sounds.
■
DBD off tone
When a D.B.D. release code is received, transpond tone
sounds.
