Encryption

Note: You must install the Secure Cryptographic Module (SCM) to use the Encryption feature.

Press the key programmed as Encryption, or access the Menu {page 12}, to switch the transceiver to secure (encrypted) transmission.

Pressing the PTT switch after the Encryption function has been turned ON encrypts the transmitted signal.

Signaling

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.

Operator Selectable Tone (OST)

If a key has been programmed with OST, you can reprogram the QT/DQT settings on each of your channels. 1 Select your desired channel.

2 Press and hold the key programmed as OST for 1 second.

3Press / to select your desired tone or code.

• Your dealer can set up to 40 tones/codes.

4Press to save your new setting.

5When you have finished operating using OST, press the OST key again to turn the OST function OFF.

Network Access Code (NAC)

Your dealer may have programmed a Network Access Code on your transceiver channels. NAC is a feature of P25 transceivers that functions similar to QT/DQT; squelch will open only when the correct NAC is received.
