1. Ensure that the gasket is properly set in the antenna base.
2. Pre-assemble the antenna to the magnetic mount by threading the antenna base onto the
mount body, making sure not to cross-thread the mount.
3. Continue tightening the antenna base until it seats to the mount.
4. Before mounting the magnetic base on the vehicle, clean both the magnet surface and the
vehicle mounting surface.
5. Place the antenna mount 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-FT in the vehicle and secure the cable.
Important! 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-FT or the antenna
when the door opens. Improper use or damage to the magnetic mount antenna or
cable can adversely affect system performance.
7. When removing the antenna, hold the antenna at the bottom of its base and tilt the antenna
mount 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 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 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.
