ETTING THE RADIO TO PASS AUDIO TO AND FROM THE
ICRI
1.
Set the radio to the channel designated by the Incident Commander.
2.
Set the audio level on each connected radio to mid-position. The radio port’s associated
LED, located on the top deck of the ICRI, will light as the received audio passes from the
radio to the ICRI.
NOTE: When the ICRI is connected to the radio via its speaker/mic jack, the radio’s internal
speaker and mic are disabled. You will be unable to hear or speak through the radio. If you can
hear or talk through the radio, the cable may not be properly attached to your radio.

ROUBLESHOOTING RADIO CONNECTION WITH
ICRI
NOTE: Before proceeding, refer to the INTEROPERABILITY DO’S AND DON’T’S for
interoperability guidelines…the solution may be there.
1.
Connect the ICRI handset to the jack labeled HANDSET, on the front of the ICRI.
NOTE: The plug on the handset appears to be similar to those provided for the radio interface
cables, but it will only fit/work properly in the ICRI’s HANDSET jack.
2.
If you have multiple radios connected to the ICRI, select one radio and turn it on. Turn
off all other radios or audio devices.
3.
Verify that the volume control on the radio is set to mid position.
4.
Depress the P-T-T bar on the side of the handset and hold it down while you speak into
the handset microphone. You should hear clean audio transmission through speakers on
the radios in the same channel as the radio connected to the ICRI.
5.
Conversely, when you key another radio on the same frequency/channel as the radio
connected to the ICRI and speak into its microphone, you should hear a clean audio
transmission through the ICRI’s handset earpiece.
6.
If you are unable to hear a clean audio transmission (a) verify the connections to the radio
and ICRI are secure, (b) the radio is indicating that it is receiving a signal from the
remote radio. Correct/adjust as needed.
7.
Next verify that the LED on the ICRI flickers with each word spoken by the remote radio
user. If it does not, slowly turn the volume control on the radio connected to the ICRI
clockwise
, stopping when the LED flickers as the remote radio user speaks.
8.
If the lack of audio at the handset is not resolved, contact C-AT Technical Support at
email: [email protected]; support is available 24/7/365.
