Making a Call with the Channel Rocker
Making a Group Call
To make a call to a group of users, your radio must be
configured as part of that group.
Procedure:
1 Press the Channel Rocker to select the channel with the
active group alias or ID.
2 Press the PTT button to make the call. The green LED lights
up. The display shows the group alias or ID, and the Group
Call icon.
3 Wait for the Talk Permit Tone to finish (if enabled) and
speak clearly into the microphone.
OR
Wait for the PTT Sidetone 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. You see the Group Call
icon, the group alias or ID, and transmitting radio alias
or ID on your display.
5 If the Channel Free Indication feature is enabled, you
will 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 Radio returns to the screen you were on prior to initiating the
call.
You can also make a Group Call via Contacts (see Making a
Group Call from Contacts on page 29).
Making a Private Call
While you can receive and/or respond to a Private Call
initiated by an authorized individual radio, your radio must
be programmed for you to initiate a Private Call.
You will hear a negative indicator tone, when you make a
Private Call via the Menu, Call Log, Contacts list, the One
Touch Access button, or the Channel Rocker, if this feature is
not enabled.
Use the Text Message or Call Alert features to contact an
individual radio. See Text Messaging Features on page 41 or
Call Alert Operation on page 35 for more information.
