■
“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 ex-
pired.
■
Clear to transpond
The transceiver waits the transpond of 5-tone/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.
■
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.
OPERATING FEATURES
■
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.
■
Busy tone
Sounds in conventional mode, when busy channel lock-
out is functioning. You can select yes or no for the optional
feature’s warning tone.
■
Group call tone
Sounds when a group call with the correct DTMF/2-tone
option signalling is received, repeats 7 times. You can se-
lect yes or no for the optional feature’s warning tone.
■
Individual call tone
Sounds when an individual call with the correct DTMF/2-
tone option signalling is received. You can select yes or no
for the optional feature’s warning tone.
■
Key press tone [A]
Sounds when a key is pressed. For toggle keys, sounds
when toggle function is turned on (key press tone [B]
sounds when it is turned off). You can select yes or no for
the optional feature’s control tone.
