“RAPID DEPLOYMENT” SETUP AND OPERATION OF THE ICRI
Setting up the ICRI for use with portable radios.
1.
Place all Talk Group switches in the
TG
position.
2.
After connecting a power source to the ICRI, turn on the ICRI so that power up and input
voltage can be verified. The green LED, labeled ―OK‖ should be lit.
If you need to use a DC source voltage between 6.5 and 7.4 volts, then neither the OK nor
the LOW (voltage) LEDs will be lit, but the ICRI will be working.
3.
Connect the handset to the ICRI jack labeled ―HANDSET‖.
4.
Connect the radio interface cables to the ICRI jacks labeled ―1‖ through ―5‖.
All five ICRI radio interface connections (1-5) are electrically identical, so it is not
important which jacks are used for conventional, trunked, repeated, encrypted or mobile
radios during ICRI operation.
5.
Connect the radio interface cables to the radios.
6.
Verify that the radios are on the channels assigned to the interoperability/bridging function.
7.
Select the Talk Group assignment for each radio, and place the switch above the associated
jack in the designated Talk Group position.
The
TG
position of the switch places any item connected with the associated port into “NO
CONNECTION” conduction without physically disconnecting the device from the ICRI.
8.
Turn on the radio connected to the jack labeled ―1‖and initially place the radio volume
controls at a mid-position between fully counter-clockwise and fully clockwise.
9.
Place the handset Talk Group selector switch in the same Talk Group as the radio connect to
jack ―1‖ so that you can transmit on that radio. You will also be able to monitor that radio.
10.
As a radio connected to the ICRI receives voice for a remote radio user for the first time,
adjust the radio‘s volume control so that the associated LED, above the jack, flickers as
words are spoken. The LED should not remain on continuously as the voice is received.
11.
Repeat 9 and 10 for each radio connected to the ICRI
12.
Connect the telephone, if it will be used.
13.
Select the talk-group the telephone and/or handset will be associated with. Place the
telephone in the ―OFF HOOK‖ position.
