Caution: The monitor must be connected before powering up the
EA_Mobile for the touch screen to function correctly.
4. Install the antennas, including GPS, on the roof of the vehicle (as shown in
Figures 2-4 and 2-5).
Caution: Use of antennas other than those supplied with the EA_Mobile
or improperly connected antennas may result in reduced
performance and/or EA_Mobile damage. Use of unauthorized
antennas will void your warranty.
• Position the antennas so they are separated by a minimum of 2 feet.
• Antennas should also be placed a minimum of 2 feet from the edge of
the vehicle or metal surface.
The transceiver antenna should be place as close to the front edge of the
vehicle as possible to get the antenna nearly vertical.
The figures below show the ideal placement of antennas mounted on
roof of a mini van and pickup. Vehicles with larger roof area can provide
greater antenna separation.
