QUIET TALK (QT)/ DIGITAL QUIET TALK (DQT)
Your dealer may have programmed QT or DQT signaling on
your transceiver channels. A QT tone/ DQT code is a
sub-audible tone/code which allows you to ignore (not hear)
calls from other parties who are using the same channel.
When a channel is set up with a QT tone or DQT code,
squelch will only open when a call containing a matching tone
or code is received. If a call containing a different tone or
code is made on the channel you are using, squelch will not
open and you will not hear the call.
Although it may seem like you have your own private channel
while using QT/ DQT, other parties can still hear your calls if
their transceiver is set up with the same tone or code.
OPERATOR SELECTABLE TONE (OST)
You can change the preset encode and decode tones for the
selected channel. Your dealer can program up to 40 tones on
your transceiver.
To turn OST ON or OFF, press the key programmed as OST.
The OST indicator ( ) appears when this function is
activated.
To change the preset encode/decode tones:
1 Press and hold the key programmed as OST for
approximately 1 second.
The OST name appears on the display.
2 Press the <B and C> keys, rotate the selector, or enter an
appropriate number using the DTMF keypad to select your
desired encode/decode pair.
3 Press the Side 1, S, or
key to accept the new setting
and return to normal operation.
