LAND MOBILE RADIO INTERFACE
NOTE: Radio interconnect cables are generally specific to a radio brand and model, although
some manufacturer’s use the same connector for several radio models. Interconnect cables
provided by C-AT have a seven digit part number label on the cable.
Connecting the interface cable to the LMR.
NOTE: Once the interface cable is connected to the radio, you will be unable to hear audio from
that radio or use the mic.
Install the radio-end of the ICRI interconnect cable onto the radio, as you would install any radio
accessory (i.e.: a shoulder speaker / microphone).
Tightening any locking screws is optional; but it is important that the connector be firmly seated
against the radio so that good electrical contact is made.
Attach the other end of the cable to any of the LAND MOBILE RADIO INTERFACE jacks, labeled
1, 2, 3, 4 and 5.
NOTE: The plug on the cable and the jack are “keyed”. Be sure to align the key before inserting
the plug on to the connector or the connection may be damaged

To connect interface cable to ICRI, align flat surface of connector to red dot on the selected ICRI port. Push
the cable onto the jack and turn clockwise until cable locks in place.
To remove the connector, push the interface cable side in towards the ICRI, and turn counterclockwise
until the cable releases. Then pull the connector straight out of the jack. Hold the barrel of the connector
rather than the cable.
