SIGNALING

Note: Signaling can be used only in Conventional FM Operation.

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. Likewise, signals

that you transmit will only be heard by parties whose QT/ DQT signaling matches

your transceiver.

If a call containing a different tone or code is made on the same 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 they set up their transceiver with the same tone or code.

■ OPERATOR SELECTABLE TONE (OST)

If a key has been programmed with Operator Selectable Tone, you can

reprogram the QT tone or DQT code on each of your channels.

3 Press the GRP and keys, rotate the CH control, or enter the list

number directly using a DTMF keypad to select your desired tone or code

from 1 to 40.

4 Press the PF 1 or DTMF key to exit OST Selection mode.

• OST is activated after seleting a list number and exiting OST Selection mode.

After selecting and setting up your desired tone or code, press the Operator

Selectable Tone key to toggle the OST function ON and OFF.
