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:
1
Select the channel with the active group alias or ID. See
Selecting a Channel on page 18.
2
Press 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.
3
Wait for the Talk Permit Tone to finish (if enabled) and
speak clearly into the microphone.
4
Release the PTT button to listen. When the target radio
responds, the green LED blinks.
5
If 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.
6
You 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:
1
Press the programmed Transmit Interrupt Remote Dekey
button.
2
The display shows Remote Dekey.
3
Wait for acknowledgment.
4
The 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.
