Futurecom MOBEXCOM DVRS User Manual page 13

Refer to this addendum when using your DVRS in a combination with the Motorola XTL5000 Digital Mobile
transmitter.
If this vehicular repeater is used in combination with a separate mobile radio transmitter, it is the responsibility
of the Repeater Operator to ensure that MPE limits are observed at all times during Repeater transmissions.
The Repeater Operator must ensure at all times that no person comes within the MPE distance from the vehicle
body to ensure compliance with the FCC's RF energy exposure limits for the general population.

Antenna Installation Instructions:
IMPORTANT NOTE: To assure optimum performance and compliance with RF Energy Safety standards, these
antenna installation guidelines and instructions are limited to metal-body vehicles with appropriate ground planes
and take into account the potential exposure of back seat passengers and bystanders outside the vehicle.
Selecting an Antenna Site/Location on a Metal Body Vehicle
1. External installation – Check the requirements of the antenna supplier and install the
vehicle antenna external to a metal body vehicle in accordance with those requirements.
2. Roof top – For optimum performance and compliance with RF Energy Safety standards,
mount the mobile radio ½  a ntenna in the center area of the roof.
3. Trunk lid – For optimum performance and compliance with RF Energy Safety standards,
mount the DVRS antenna in the center area of the trunk.
Before installing an antenna on the trunk lid,
- Be sure that the distance from the antenna location on the trunk lid will be at least 85 cm
(33 inches) from the front surface of the rear seat-back to assure compliance with RF Energy Safety standards.
- Ensure that the trunk lid is grounded by connecting grounding straps between the trunk lid
and the vehicle chassis.
4. Ensure that the antenna cable can be easily routed to the radio. Route the antenna cable as
far away as possible from any vehicle electronic control units and associated wiring.
5. Check the antenna location for any electrical interference.
6. Ensure that any other mobile radio antenna on this vehicle is at least one foot (30.48 cm)
away from the DVRS and mobile radio antenna.
NOTE: Any two metal pieces rubbing against each other (such as seat springs, shift levers, trunk and hood lids,
exhaust pipes, etc.) in close proximity to the antenna can cause severe receiver interference.
