Certain radio telephones or land mobile radios also known as radio transceivers), or
the way in which they are installed, may adversely affect various vehicle operations
such as engine performance, driver information, entertainment and electrical
systems.
Expenses incurred to protect the vehicle systems from any adverse effects of any
such installation are not the responsibility of Navistar Corporation.
The following are general guidelines for installing a radio transceiver in Navistar
vehicles. These guidelines are intended to supplement, but not to be used in place
of, detailed instructions which are the sole responsibility of the manufacturer of the
involved radio transceiver. Although this document refers to passenger vehicles, the
same general guidelines apply to trucks.
Important: Refer to the illustrations found later in this bulletin for aid in installation.
8.1. Transceiver Location
Locate transceiver for remote radios on driver
’s side of trunk as near to
the vehicle body side as possible.
One-piece transceivers should be mounted under the dash or on
transmission hump where they will not interfere with vehicle controls or
passenger movement.
Great care should be taken not to mount any transceivers, microphones,
speakers or any other item in the deployment path of a Supplemental
Inflatable Restraint (air bag).
8.2. Antenna Installation
Each vehicle model and body style reacts to radio frequency energy
differently. When dealing with an unfamiliar vehicle, it is suggested that a
magnetic-mount antenna be used to check the proposed antenna location
for unwanted effects on the vehicle. Antenna location is a major factor in
these effects.
The antenna should be a permanent-mount type located in the center of
the roof or center of the rear deck lid. Glass mounted antennas should be
kept as high as possible in the center of the rear window or windshield. If a
magnet-mount antenna is used, care should be taken to mount the
antenna in the same location as a permanent-mount type. If a disguise-
mount antenna is used, great care should be taken to shield any tuning
network from vehicle electronics and wiring, or to mount the tuning
network in an area completely clear of vehicle electronics and wiring.
Standard metal mount antennas may be mounted on a vehicle with
nonmetallic body panels by two methods. Most nonmetallic skinned
vehicles have metal frames underneath. Mounting the antenna near a
