• Position the control head so that the driver / operator can have easy view and access to the display and
controls.
• The radio should be located as to not interfere with driver and passenger movement or inhibit the
movement or adjustment of vehicle seats.
• Locate the radio and any associated equipment out of the vehicle’s airbag zone.
• A microphone hang-up clip is provided as part of the installation kit. This should be located to provide
convenient access to the driver / operator, yet not interfere with any vehicle controls.
• Installations in certain harsh environments may require using best practices to protect the equipment,
including the following:
Ø Position the equipment to avoid direct impact from water and hose-down, snow, dust, smoke, gases,
road debris, oils, chemicals and corrosive agents.
Ø Installation behind a door or cover in a protective enclosure (must provide adequate airflow and
cooling).
Ø Use splash guards, shields, or covers, to protect against direct impacts.
Ø Refer to the Caring for The Radio Equipment section on page 95 for additional information.
6.3.2 Power Source Location and Considerations
• Some vehicles operate on 24 VDC so it is important that the location chosen is a 12 VDC source. If a
12 VDC source is not available, a converter must be installed.
• Ensure that the location chosen is a main power source, allows the addition of added terminals, and
supports the needed current draw.
• If an auxiliary fuse block is going to be used, ensure that the location chosen for the block guards
against possible short circuits.
• Some vehicles, e.g., trucks, have studs on the firewall that can be used to pass power without the need
for a through hole. These can be used only if verified that they are not used to connect data cables or
wires.
6.3.3 Ignition Sense Location and Considerations
Chose an ignition sense that does not interfere with the safety related systems of the vehicle.
The ignition sense wire (white wire) connection determines how or when power is applied to the mobile
radio. The white wire is sometimes referred to as the “white ignition switch wire” or the “ignition sense
input wire.”
There are three configurations for using of the ignition sense wire to power the mobile radio:
• The mobile radio is powered on and off with the vehicle ignition. See Section 6.3.3.1.
• The mobile radio is powered on and off with a master switch or timer. See Section 6.3.3.2.
• The mobile radio wired hot, power always applied to the mobile radio. See Section 6.3.3.3.
In a front-mount or remote-mount configuration, the ignition sense wire is part of the radio’s and Control
Head’s power cable.
Regardless of the configuration, the radio’s main DC power input (red A+ wire) must be connected through
an in-line fuse to unswitched vehicle DC power. The red wire must be connected to raw battery power
(positive battery terminal) via the supplied fuse. It is important to use the proper crimp tool for crimping
any terminals or fuse holder.
