Receiving and Responding to a Talkgroup Call
To receive a call from a group of users, your radio must be
configured as part of that talkgroup.
Procedure:
When you receive a talkgroup call (while on the Home screen),
depending on how your radio is preprogrammed:
1 ASTRO Conventional Only:
The LED lights up solid yellow. The display shows the
talkgroup alias or ID, and the caller alias or ID.
OR
Trunking Only:
The display shows the caller alias or ID.
2 Hold the microphone vertically 1 to 2 inches (2.5 to 5.0 cm)
from your mouth.
3 Press the PTT button to respond to the call. The LED lights
up solid red.
4 Release the PTT button to listen.
See Making a Talkgroup Call on page 30 for details on making
a Talkgroup Call.
Receiving and Responding to a Private Call
(Trunking Only)
A Private Call is a call from an individual radio to another
individual radio.
These one-to-one calls between two radios are not heard by
others in the current talkgroup. The calling radio automatically
verifies that the receiving radio is active on the system and can
display the caller ID.
Note: If the feature inactivity timer is enabled, your radio
automatically exits the feature when your radio is left
idle long enough for the time to expire. You will hear
the Menu Inactive Exit Tone upon feature exit.
Procedure:
When you receive a Private Call:
1 You hear two alert tones and the LED blinks green. The
display shows CALL RECEIVED and the caller alias or ID.
2 Press the Menu Select button directly below RESP within 20
seconds after the call indicators begin.
3 During the call, the display shows the caller alias (name), if it
is in the call list.
OR
During the call, the display shows the caller ID (number), if
the caller’s name is not in the call list.
