5. Place the antenna base on the vehicle where it is flat and ensure that the entire magnet is
making secure contact with the vehicle.
6. Route the antenna cable through an open window or door and secure it in such a way that it
will not be accidentally pinched and kinked or damaged. Complete the cable routing to the
IMR-XA in the vehicle and secure the cable.
Note: If the vehicle door must be opened with the cable in place,
make sure to leave enough slack in the cable so as not to pull on the
IMR-XA when the door opens.
7. When removing the antenna, hold the antenna at the bottom of its base and tilt the antenna
to release the magnetic force. Do not pull on the coaxial cable to release the magnetic force
and do not drag the magnet across the surface of the vehicle.
Installing the DC Power Cable
The DC power supply cable connects to the vehicle's electrical system so you can easily con-
nect and disconnect power for the IMR-XA or 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. If preferred, the accessory adapter may be cut off and the unter-
minated 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 illustrations show the vehicle accessory adapter and the unterminated end of
the power supply cable with the accessory adapter removed. Notice the polarity and marking
of the power supply cable wires.
