If an existing hole is not conveniently located for passing the power ca-
ble through the fire wall, drill a hole and insert the rubber grommet pro-
vided. Leave at least 18 inches of slack in the plug end of the cables next to
the radio. A typical cable routing diagram is shown in Figure 4.
MOUNTING THE RADIO
The radio should be mounted within convenient reach of the operator.
Mount the radio where it will not interfere with the safe operation of the ve-
hicle or cause a hazard to passengers in case of an accident. Refer to Figure
5 for details on securing the mounting bracket.
The mounting bracket may be placed over or under the radio housing de-
pending on the mounting location. Additionally, the radio may be tilted
within the mounting bracket to allow the best viewing angle.
POWER CABLE INSTALLATION
Power connections to the radio are made through a three-wire power ca-
ble assembly (Figure 6).

Radio installation in vehicles powered by liquefied petroleum gas, with
the LP gas container in the trunk or other sealed-off space within the interior
of the vehicle, must conform to the National Fire Protection Association
Standard NFPA58 which requires that:
•
Space containing radio equipment shall be isolated by a seal from the
space containing the LP gas container and its fittings.
•
Outside filling connections shall be used for the LP gas container.
•
The LP gas container space shall be vented to the outside of the
vehicle.
RADIO CONFIGURATION
Before installing the radio or making any electrical connections, it is nec-
essary to configure jumpers on the internal circuit card assemblies in order
to support the selected options. Refer to Table 1 and the maintenance manual
for information. Only the installed options should be enabled. The FMD
System model does not have a speaker within the radio due to the position-
ing of the keypad, therefore it comes standard with the remote internal
speaker option. Connector option FMCN1B or Connector/Cable option
FMCC5J must be specified when ordering the FMD System model in order
to install the supplied speaker. The particular connector and cable option will
depend on the combination of options and the planned installation. System
model radios do not require the removal of panel control board jumper C.
The following options are currently available for use with the FMD radio.
•
External speaker
•
Remote internal speaker
•
Emergency switch
•
Bypass ignition switch
