Making a Selective Call

Just like a Private Call, while you can receive and/or respond to a Selective Call initiated by an authorized individual radio, your radio must be programmed for you to initiate a Selective Call.

Procedure:

1Select the channel with the active group alias or ID. See Selecting a Channel on page 18.

2Press the PTT button to make the call. The green LED lights up. The Private Call icon appears in the top right corner. The first text line shows the subscriber alias. The second text line displays the call status.

3Wait for the Talk Permit Tone to finish (if enabled) and speak clearly into the microphone.

4Release the PTT button to listen. When the target radio responds, the green LED blinks.

5If the Channel Free Indication feature is enabled, you hear a short alert tone the moment the target radio releases the PTT button, indicating the channel is free for you to respond. Press the PTT button to respond.

OR

If there is no voice activity for a predetermined period of time, the call ends.

6You hear a short tone. The display shows Call Ended.

Stopping a Radio Call

This feature allows you to stop an ongoing Group or Private Call to free the channel for transmission. For example, when a radio experiences a “stuck microphone” condition where the PTT button is inadvertently pressed by the user.

Your radio must be programmed to allow you to use this feature.

Procedure:

While on the required channel:

1Press the programmed Transmit Interrupt Remote Dekey button.

2The display shows Remote Dekey.

3Wait for acknowledgment.

4The radio sounds a positive indicator tone and the display shows Remote Dekey Success, indicating that the channel is now free.

OR

The radio sounds a negative indicator tone and the display shows Remote Dekey Failed.

On the interrupted radio, the display shows

Call Interrupted, and the radio sounds a negative indicator tone until you release the PTT button, if it is transmitting an interruptible call that is stopped via this feature.
