damage to your vehicle which may result in death or serious injury.
You must read this manual before starting the installation!
You must also read and observe the safety information on radio
operation provided in the safety and compliance information and
the user’s guide!
RF Exposure Hazard
To comply with FCC RF exposure limits:
For radios with a transmit power of 30-50W:
■VHF radios must be installed using an antenna mounted centrally on the
vehicle roof, with a gain of 2.15dBi or 5.15dBi.
■UHF and 800MHz radios must be installed using an antenna mounted
either centrally on the roof with a gain of 2.15dBi or 5.65dBi, or
centrally mounted on the trunk with a gain of 5.65dBi.
For radios with a transmit power of 25W:
■The radio must be installed using an externally mounted antenna with a
gain of either 2.15dBi or 5.15dBi.
In all cases, an antenna must not be mounted at a location such that any
person or persons can come closer than 35 inches (0.9m) to the antenna.
Health Canada
Warning Statement
The installer of this radio equipment must ensure that the antenna is located
or pointed such that it does not emit RF field in excess of Health Canada
limits for the general population; consult Safety Code 6, obtainable from
the Health Canada website http://www.hc-sc.gc.ca.
Vehicle Manufacturer’s Installation Instructions
Installation of this product in a vehicle must be performed according to the
instructions provided by the vehicle manufacturer. For more information,

MPT 1362 Code of Practice
Mobile radios should be installed in accordance with the MPT 1362 Code
of Practice.
Safe Radio Mounting
Warning Mount the radio securely so that it will not break loose
in the event of a collision. An unsecured radio is dangerous to the
vehicle occupants.
■Mount the radio and the microphone where they will not
interfere with the deployment of passenger airbags, the
vehicle operator controls, the vehicle operator’s view.
■Do not mount the radio vertically, with the control head
facing down. This will violate compliance with the standards
UL/CSA/EN 60950, Safety of Information Technology
Equipment.
Caution The bottom surface of the radio and the heatsink fins can
become hot during prolonged operation. When installing the radio,
position the radio so that it is not possible for the radio user to touch the
bottom surface of the radio and the heatsink fins.
Interference with Vehicular Electronics
Warning Some vehicular electronic devices may be prone to
malfunction due to the lack of protection from RF energy when
your radio is transmitting.
Examples of vehicular electronic devices that may be affected by RF
energy are:
■electronic fuel injection systems
■electronic anti-skid braking systems
■electronic cruise control systems
■indicators.
If the vehicle contains such equipment, consult the vehicle manufacturer or
dealer to determine whether these electronic circuits will perform normally
when the radio is transmitting.

TM9456 Dual-Radio Installation and Programming Guide 11

Preparation when Drilling Holes
Warning When drilling holes in the vehicle, check that drilling
at the selected points will not damage existing wiring, petrol tanks,
fuel lines, brake pipes, or battery cables.
Vehicles Powered by Liquefied Petroleum Gas
Warning Radio installation in vehicles powered by LPG (lique-
fied petroleum gas) with the LPG container in a sealed-off space
within the interior of the vehicle must conform to the National Fire
Protection Association Standard NFPA 58. This standard states
that the radio equipment installation must meet the following
requirements:
■The space containing the radio equipment shall be isolated by
a seal from the space containing the LPG container and its
fitting.
■Outside filling connections shall be used for the LPG
container and its fittings.
■The LPG container space shall be vented to the outside of
the vehicle.
Non-standard Radio Installations
The installation U-bracket has been designed so that there is enough
airflow around the radio body to provide cooling.
If a non-standard installation method is used, care must be taken that
sufficient heat can be dissipated from the heatsink fins and the ridged
bottom surface of the radio.
For this to be achieved, there must be a gap of more than 3/8 inch (10 mm)
between the bottom surface of the radio chassis and the mounting surface.
This is illustrated in the following diagram:
10 mm (3/8 in.)
mounting surface

IP54 Protection Class Considerations
A dual-radio system fulfils the requirements of the IP54 protection class.
Notice However, do not mount the radio in areas where it can be tem-
porarily submerged from an accumulation of water or other liquids (e.g.
when using a high-pressure cleaning device).
The IP54 protection class does not apply when:
■a remote interface is removed from the radio body or control head.
■the bungs are removed from the auxiliary connector or the cavity for the
external options connector (fitting an auxiliary connector or external
options connector will not restore the IP54 protection class)
■a grommet is not installed. For example, grommets on the radio
connecting cable, control-head remote cable, and microphone cord.
■adding an accessory that is not rated to IP54, for example, a control-
head interface box, or hand-held control-head remote interface box.
Negative Earth Supply
The radios are designed to operate only in a negative earth system.

Notice The dual body solution will only operate as a system. The cor-
rect radio body interface must be connected to the corresponding radio,
and both radios and body remote interfaces must be connected before
the system will operate.
1.6 Removing and Installing Grommets
Grommets ensure that the radio system and all connections are sealed
against water, dust and other environmental hazards. A dual-radio system
requires a grommet in the unused remote-interface port (item g in
Figure 1.2 on page 17). A dual-radio system also requires all cable
grommets to be installed.
Removing a
grommet
1. Using your thumb or forefinger, lift up one of the corners of the
microphone grommet. Firmly (but gently) pull that corner until the
seal comes away from the cavity. See Figure 1.2.
Figure 1.2 Removing a grommet
2. Repeat to expose another corner.
3. Pull the exposed corners back and remove the grommet.
4. If removing a cable grommet, slide the grommet along the cable to
reveal the plug.
Installing grommets 1. If installing a cable grommet, slide the grommet along the cable.
2. Push two adjacent corners of the grommet into the socket cavity.

2.2 Checking the Firmware Versions and Software
Features
Check that the firmware version of all devices (radio bodies and control
head) is the same. If not, upgrade the appropriate devices by connecting the
control head directly to a radio body. For the firmware version and
programming application version to use, see “Hardware and Firmware
Compatibility” on page 15. For more information, click the Help [?] button
from the programming application’s Download dialog (Tools >
Download).
Check that both radio bodies have the software feature for Multi-Body
Support enabled (default factory configuration). For more information,
click the Help button from the programming application’s Optional
Features dialog (Tools > Optional Features).
2.3 Downloading Network IDs
The Head and Bodies forming the radio system must have a unique NTID
(Network ID) to successfully operate together. The following outlines the
NTID requirements for a dual body, single control head system.
If a dual body radio system has been ordered as a factory kit the NTIDs
will be correctly pre-configured.
The “Duplicate MAC Address” error indicates a problem with NTID
configuration.
If both devices have a standard configuration, the only required change
is to switch the VHF body NTID from 1 to 3.
NTIDs can only be set with a single body connected to the control head.
If connecting using the body remote interface, only the T02-00081-
BAAA interface can be used. This interface has bias fitted.
Note Only items for connected devices will be displayed.
12. For each body requiring an NTID update, connect the control head
(the T02-00081-BAAA remote interface must be used) and apply
power.
