RADIO OPERATOR
Futurecom requires the MOBEXCOM DVE operator to ensure FCC Requirements for Radio Frequency
Exposure are met. The DVE output power has to be set such that the maximum power into 0dBd
(2.15dBi) omni directional antenna does not exceed 3.0W at the antenna connector. The minimum
distance between all possible personnel and the antenna at 3.0W must be at least as shown in Table 1.
FAILURE TO OBSERVE THE MPE DISTANCE EXCLUSION AREA AROUND THE ANTENNA MAY
EXPOSE PERSONS WITHIN THIS AREA TO RF ENERGY ABOVE THE FCC EXPOSURE LIMIT FOR
BYSTANDERS (GENERAL POPULATION). IT IS THE RESPONSIBILITY OF THE OPERATOR TO
ENSURE THAT MPE LIMITS ARE OBSERVED AT ALL TIMES DURING TRANSMISSIONS. THE
OPERATOR MUST ENSURE AT ALL TIMES THAT NO PERSON COMES WITHIN MPE DISTANCE FROM
THE ANTENNA.
ATTENTION!
The MOBEXCOM DVE is intended for use in occupational / controlled conditions, where users have
full knowledge of their exposure and can exercise control over their exposure to meet FCC limits. This
radio is NOT authorized for general population, consumer, or any other use.
ANTENNA INSTALLATION
IMPORTANT
The maximum allowed gain of the λ/4 omni-directional antenna for the Mobexcom DVE is Unity (0dBd).
IMPORTANT
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
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.
Roof top
For optimum performance and compliance with RF Energy Safety standards, mount the mobile radio antenna
in the center area of the roof.
