Power
 AA Battery Power
 AC Power
 DC Power
“AA” Battery Pack
 Accepts 8 “AA” batteries
 24+ hours of continuous operation
 LEDs indicate input voltage.
 Use fresh alkaline batteries
The battery housing is comprised of two parts; the cover and an internal tray.
NO TOOLS ARE NEEDED TO REMOVE THE cover AND REPLACE THE BATTERIES.
AC Power
 Accepts 115 VAC– 220VAC
 Two pin locking connector
Note: Align the plug’s “key”
with the jack’s “keyway” before
attempting to insert the plug.
DC Power
 Accepts 7-20V
 Two pin locking connector
 Cigarette lighter
 Alligator clips
ICRI handset
 Compatible with the C-AT handset
 Connection and controls on the front of the ICRI
 Maybe replaced with a headset for hands-free operation
 Use as an:
 Incident Commander interface
 Troubleshooting tool
 Setup tool
Land Mobile Radio Interface – Pt. 1
 Verify Radio
 Operation
 Batteries
 TX/RX
NOTE: Radio interconnect cables are generally specific
to a commercial radio brand and model, although some
manufacturers use the same connector for several radio
models. Interconnect cables provided by C-AT have a
seven digit part number label on the cable.

Land Mobile Radio Interface – Pt. 2
 Attach interface cable
 Select Talk Group
 Verify LED lights
 Mobile radios
NOTE: Connect each radio separately to the ICRI, use
the provided handset to verify the radio is functioning
before connecting the next radio.
Telephone Interface
 cellular*

Inter-Agency Communications
Status Status Board
Bridge Unit ID®
(option)
 In response to the critical disruption of radio communications that can
occur when more than one "bridge" device links radios with identical
frequencies, causing heterodyning, C-AT has developed the Bridge Unit ID
for the ICRIs.
 The “announcement” radically simplify the task of locating the owner of
the interfering bridge and in shutting the device down.
 The Bridge Unit ID is a digitized speech message selected by the user
organization / agency. The “ID” is transmitted when the ICRI is first
powered up on all talk groups, and then at preset intervals of 0, 5, 10, or
15 minutes.
 The announcement automatically “skips” a
broadcast if there is any radio activity at the
interval mark.
ICRI use with 250’/500’ cable-reels to extend radio
coverable in building, tunnels, and shipboard (option)

Talk Around CH “A”
Problem: Ability of radio used by Recon Commander to receive
signals from assigned radio frequency used by his Entry Team is
substantially reduced when another in-band radio is “keyed” by
LE Commander transmitting to his Entry Team personnel.
Strong
Signal
Cause: The closer LE Commander is to Recon Commander, the
more severe the “desensing” of the Recon Cmdr’s radio. The less
the frequency separation between radios “A” and “B”, the more
severe the desensing will be.
