Theory of Operation
The ICRI/2PE and ICRI/2PED are limited function versions of the ICRI (P/N 500.9250). These
units can provide a communications bridge, or link, between two public safety agencies with
otherwise incompatible radios. The ICRI/2PE and ICRI/2PED can quickly establish the link as a
tactical situation rapidly unfolds. As with all ICRIs, they require minimal resources to move it into
place, to enable it initially, or to maintain its operation over manyhours. The units will provide full
operational capabilities moments after arrival on-scene, and the remain operational for 30+ hours
powered by internal 6 “AA” batteries.
The ICRI/2PE and ICRI/2PED perform two primary functions for public safety personnel:
Distributes the audio received from one two-way radio, handset/headset, or telephone, to
other devices connected to the unit.
Utilizes this same incoming audio to “key” the other radios or telephones connected to the
ICRI. The radios can be portables, mobile, NEXTEL “Direct Connect” phones or a
combination. Land-line telephones, cell phones, STU, STE or satellite phones can also be
connected to the ICRI.
The ICRI/2PE and ICRI/2PED do not discriminate or evaluate the incoming audio, so that
unnecessarydelays are not inserted into the audio transfer or “keying” processes. Radios, telephones
and/or recording devices connected to the ICRIare provided with the incoming audio, essentiallyin
real-time. A “buffer” preserves the first syllables of incoming audio while the transmitters are
keying up “trunking” radio systems to provide radio channel access.
These versions of the ICRI contain 2 circuits that keythe radios connected to the ICRI;thesecircuits
are commonly referred to as “VOX” or “voice-activated switches.” The ICRI uses these circuits to
perform other controlling functions as well. Onlythe VOXdirectlyconnectedtotheincomingaudio
is used to keyeach of the other radios simultaneously(all other are temporarilydisabled, preventing
a second “voice” from causing a disruption of communication).
The ICRI/2PE and ICRI/2PED are functionally identical. The difference between thetwounitsis the
depth of the 2PED is greater. This provides the user enough space on the top of the unit to carry
interface cables with the unit. The greater depth also provides room for an external power jack on
the 2PED not present on the 2PE.

Pre-Operational Activities
Some pre-planning is necessary to ready the ICRI for rapid deployment. The following should be
accounted for before placing the ICRI on-line:
1. Determine what the power source will be for the ICRI. Verify that “fresh,” AA, alkaline
batteries are available or that one of the external power sources are available.
2. Determine what brand and model of radios will be connected to the ICRI and that an
“interface” cable for each radio is available.
3. If radios are not maintained with the ICRI, advise agencies that they will need to supply a
“spare” radio, for the radio interoperability.
4. Verify that the radios are known to operate properly and have at least one fully charged
battery or other reliable power source.
The ICRI/2PE and ICRI/2PED can be powered byaninternal 6 “AA” battery assembly oranexternal
DC source up to 20 VDC.
Among the power sources that can be used to power the ICRI are:
12 volt vehicle battery
Vehicle cigarette lighter
115v AC (with an external adapter)
BA590 “military”
Commercial dry-cell or other battery (7.2V or greater)
C-AT 12 volt battery pack (uses 8 “AA” batteries)
Internal 6 “AA” battery assembly
The ICRI’s internal regulated power supply is reverse polarityprotected, but it is important to check
polarity of DC supplies before connecting them to the ICRI.

1. Set-up and Use Instructions
As a minimum, the following will be required for ICRI operation:
ICRI assembly
6 “AA” alkaline batteries or power supply with interconnect cable to ICRI
Two radio interface cables or a radio interface cable and a cell phone cable (no external
cable needed for land-line phone connection)
Two radios and/or a phone
Insert “AA” batteries into the housing on the internal panel of the ICRI-2PED.
Turn on power, OK LED should come and stay lit. This will provide at least 24 hours of continuous
use.
Check the radios’transmit and receive functions, battery and channel selection.
Connect one interface cable to the ICRI and one LMR
Connect the handset.
Set the volume controls for the radios and handset to a middle position.
NOTE: The audio will be disabled on the radio when theinterconnect cablehasbeen attached,so
you must use the handset, or a second radio on the same channel to verify link.
Active VOX will light when the radio is transmitting.
Repeat with the other radio/phone to be used.

Setting the radio to transmit through the ICRI
Set the audio level on each connected radios to mid position.
NOTE: Radio interconnect cables are generally specific to a radio brand and model, although
Set the radio to the desired channel.
Because the ICRI is connected to the radio via the speaker jack, the audio path on the attached radio
is disrupted. You will be unable to hear or speak through that radio. If you can hear or talk through
the radio, the cable may not be properly attached to your radio.
The LED on the internal panel “Active VOX” will light as audio is transmitted from the radio
through the ICRI.
If the users are having difficultytransmittingbetween disparate radios/channels, usethe local handset
to test the audio.
Connect the local handset to the jack on the front of the ICRI labeled, HANDSET. The jack on the
handset is similar to those provided for the radio cables. The handset connector contains more pins
and is designed to be the only cable used in the HANDSET jack.
After connecting the handset, set the volume knob to mid position, set the talk group switches
(located directlyabove the corresponding radio connection) to the same position as the other radios
being used.
Depress the P-T-T bar on the inside of the handset to speak. The LEDs on the internal panel “Active
VOX” ports in use should light. If they remain solidly lit, turn down the volume. If the LEDs do
not light:
Slowly increase the volume settings.
Check to make sure the cable is solidly connected to the radio and the ICRI.
Make certain the radio has a charged battery.
Check if the radio can function normally with a speaker mic attached.
Operating the portable radio after cable connection
After a radio is connected to the ICRI, the radio’s internal speaker andmicrophonearedisabled. The
user will be unable to hear any audio or speak from the connected radio.
To verifythe radio is transmitting and receiving properly, use the localhandset (SeeSection6.Using
the Local Handset)

Using a Nextel™ phone in DirectConnect™ mode.
When connecting a Nextel handset, theconnection ismadethroughthehandset's "headset"jack. This
connection is the 2.5mm jack on the Nextel Falcon (i530) series phones/handsets.
NOTE: At this point, the speaker and mic of the Nextel have been disabled; you will be able to
communicate through the ICRI handset.
Connect the other end of the interconnect cable to either LAND MOBILE RADIO INTERFACE
jack on the ICRI.
Set the Nextel into DirectConnect mode and program the desired Nextel “talkgroup” or
DirectConnect number.
Program the phone to stay in DirectConnect mode (See Nextel manual for directions).
NOTE: A Nextel i90 series phone should not be connected to an ICRI for DirectConnect
operation. Software in the i90 is not compatible with radio interoperability.
Audio received from the other connected radios or the ICRI handset will be heard byNextel phone
users via the Nextel network.
