Receiving and Responding to a Radio Call
Once you have selected the required channel and/or zone, you
can proceed to receive and respond to calls.
You see solid red while the radio is transmitting, and solid
yellow when the radio is receiving a transmission (conventional
mode only). There is no LED indication when the radio receives
a transmission in trunking mode.
If the radio is receiving a secure transmission, the LED blinks
yellow.
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 32 for details on making
a Talkgroup Call.
