Installation Instructions

8F083X03 Rev 16.2
DVRS-Product Safety and RF Exposure Booklet 28
Do not install the trunk antenna if the distance between the back seat
passenger and the trunk mount antenna is less than 85cm.
4. Mounting restrictions for certain radio models.
NOTE: Do not cut antenna cables to ensure compliance with RF Energy Exposure regulations
NOTE: VHF and UHF 1/4 wave antenna should be mounted on the roof, not on the trunk lid, to
ensure compliance with RF Energy Exposure regulations.
5. 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.
6. Check the antenna location for any electrical interference.
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.
Fig 3 Multiple Antennas Separation for locations 1-10
Fig. 3 indicates the separation distances required for the various antennas used with an APX
8500 midpower radio. Each "cross-hair" symbol represents a possible location (i.e. LOC) of an
antenna. The recommendation is to locate them as close to the center of the roof and/or trunk as
possible, without interference with a lightbar. This picture is not drawn to scale. For letters A, B, C,
and D, the table indicates the EXACT distance for separation of the LMR antennas. For letters E,
F, G, and H, the table indicates the maximum distance between the edge of the ground plane and
the accessory antenna location.
NOTE:
• A minimum of 18 inch (46cm) separation is required between lightbar and any roof mounted
antennas, to prevent interference with the lightbar circuitry (see lightbar manufacturer’s installation
information).
