antenna. Reinstall and reconnect the IMR-FT in the vehicle. Follow the instructions found
in Installing the IMR-FT in the Mounting Jacket on page 32.
Note: Antenna connectors should only be finger-tightened. Do not tighten the connectors
with a tool.
Installing the DC Power Cable
The DC power supply cable connects to the vehicle's electrical system so you can easily
connect and disconnect power for the IMR-FT. The DC power cable is shipped with a vehicle
accessory (12V) adapter attached so the cable and the IMR can be easily moved between
different vehicles. The accessory adapter comes with a replaceable five amp fuse installed. If
preferred, the accessory adapter may be cut off and the unterminated end of the cable
hardwired permanently to the vehicle fuse block or other 12V DC power source, so the cable
remains in the vehicle. The IMR is still removable.
The following images show the unterminated end of the power supply cable with the
accessory adapter removed and the vehicle accessory adapter. Notice the polarity and
marking of the power supply cable wires.

Power Cable Routing - All Installations
1. Once the mounting location of the IMR-FT is known, select a location in the vehicle for the
IMR connector end of the cable so that it reaches the Itron Mobile Radio power jack
without putting stress on the cable or radio.
2. Route the vehicle accessory adapter end of the cable to the desired voltage and grounding
sites in the vehicle, typically either an accessory jack for a removable installation or the
fuse block for a permanent installation. Leave enough slack in the cable to work with it and
