TK-782
" "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)
The transceiver is capable to have "OST" function and 16
tone pair (QT/DQT) with max 10-digit name for each tone
pair.
! "OST" back up
The transceiver is programmable the selected "OST" code
is memorized or not. If you set to Disable (no memorized),
the "OST" function always starts at "off".
" Clear to transpond
The transceiver waits the transpond of DTMF if channel is
busy until channel open. This feature prevents the interfer-
ence to other party.
5. Option Signalling (DTMF)
Built-in DTMF decoder is available for option signalling.
It is possible to use individual call, group call, stun, kill.
Stun and kill are used with DTMF .
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
( ) will flash and option signalling will be released. The
*
transpond or alert tone will sound.
If the selective call alert LED is set up, the orange LED will
flash.
While option signalling matches (or if option signalling is
deactivated when you are transmitting), you can mute or
unmute ID/QT/DQT/Carrier.
" AND/OR
Option signalling match conditions can be selected with
AND/OR logic.
AND Triggers at match with QT/DQT/ID+DTMF; Both
OR Triggers only for match with DTMF; Option
AND Triggers at match with QT/DQT/ID+DTMF; Both
OR Triggers only for match with QT/DQT/ID; Signalling
Even if set for OR, AF mute cannot be canceled just by a
match with DTMF.
In channels not set with QT/DQT, signalling is a match
just by rceiving the carrier.
