5 Installation
This section describes the installation of 3M™
Opticom™ GPS Priority Control System vehicle
equipment.
Please read and fully understand the following
paragraphs before starting the installation.
??
Before cutting or drilling any openings in the
vehicle or lightbar, draw a diagram showing
placement, measurements, and dimensions. Use
the diagram to avoid drilling or cutting holes in
undesirable locations.
??
Always follow the vehicle manufacturer's
recommendations for modification, alteration,
and installation or connection of accessories or
equipment to the vehicle and lightbar.
??
Installation on specialty vehicles (such as
motorcycles, parking enforcement, utility, and
special maintenance vehicles) requires
particular care and attention to details.
??
Do not mount the radio/GPS antenna within 18
inches of any other radio antenna. Follow the
installation instructions to avoid possible radio
frequency interference problems.
??
The radio/GPS unit is not watertight;
therefore it should be mounted inside the
passenger compartment or some other
protected area of the vehicle.
??
The radio/GPS antenna should be mounted level
and as high on the vehicle as possible. The
radio/GPS antenna should have an unobstructed
view of at least 50% of the sky.
??
The radio/GPS antenna must not be obstructed
by lightbars, speakers, antennas, or other devices
especially towards the front of the vehicle.
??
If necessary an alternate mounting bracket is
available for mounting on vehicle mirrors and
vertical posts. This bracket is available from
Mobile Mark Communications Antennas
(www.mobilemark.com, 1-800-648-2800). The
part number is SM-MM, price is approximately
$15.
??
Wires that are routed under carpets or mats
should be run between the pad and the carpet.
This will minimize abrasion and heat damage
from catalytic converters.
??
Protect cables with armor or sheathing when they
are routed around sharp corners and edges.
Avoid routing cables through potential pinch
points. Clamp or tie all cables in place. Route
and secure cables well away from moving parts.
??
Do not paint the radio/GPS antenna cover. Metals
or metal oxides in the paint may interfere with
GPS reception and/or radio reception and
transmission.
??
Do not modify the radio/GPS unit circuitry. There
are no user serviceable parts inside.
IMPORTANT NOTE
Modifying the radio/GPS unit may seriously
damage the equipment and void the
warranty.
Do not attempt to modify the
radio/GPS circuitry in any way. Modifying
the radio and/or antenna in any way may
cause the radio to violate FCC requirements.
