Portable 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. A chart, crossing these
numbers with the radio brands/models appear in Appendix A of this manual. Contact C-AT for
set-up instructions for your specific mobile radios.
Connecting the portable radio
Connect the radio specific end of the ICRI interconnect cable onto the radio, as you would install a
speaker/microphone.
If present, tighten connector locking screws (optional); it is important that the connector be firmly
seated against the electrical terminals on the body of the radio, so that good electrical contact is
made.
Connect the other end of the interconnect cable to RADIO INTERFACE jacks labeled “1” or “2”.
NOTE: The plug on the interconnect cable and the jack on the ICRI are “keyed”. Be sure to
align the key before inserting the plug on to the connector or the connection may be damaged.
After the plug is fully seated on the jack, the locking ring on the plug should be turned clockwise
until the ring cannot be turned further---about one-eighth (45
o
) of a turn.
