Introduction

Introduction
This manual covers the installation procedures for ASTRO mobile and motorcycle radios with O2, O3,
O5, O7, and O9 control heads and accessories required to complete the radio system.
The radio system consists of a control head, radio, antenna, microphone, speaker, cabling, Universal
Relay Controller (URC), and accessories.

1.1
Mobile Radio Description
This chapter covers the basic dimension of the mobile radio.

1.1.1
Dimensions
When installing the radio, make sure to plan the installation carefully and leave extra room in the rear
of the radio for cabling and accessory connections. Leave extra space in the front of the radio for
access, controls, and cabling (if remote mount) and to the sides of the radio so that you can access
and install the trunnion screws/wing screws.
NOTICE: The rear accessory connector adds 0.75 in. to the overall length. The remote mount
length is 244 mm.

Introduction

1.2
Standard Configurations
This chapter covers the dash mount, remote mount, and multi-control head configurations.

1.2.1
Dash Mount Configuration
There are two versions of the mobile dash mount.
The first are the O2, O5, and O7 control heads which are mounted on the front of the transceiver
housing. The second is the O3 control head which is connected to the transceiver through a coiled
cable, which is plugged into the CAN connector on the transceiver.
Electrical connection between the two takes place within the radio through a flexible circuit board
between the connectors on the front of the transceiver and at the back of the control head for O2, O5,
and O7 and between the connectors on the front of the transceiver and at the back of the TIB for the
O3.

1.2.2
Remote Mount Configuration
In the remote control version, the transceiver and the control head are mounted separately in the
vehicle.
The O2, O5, and O7 control heads are mounted in remote trunnions near the operator. The O3 and O9
control heads are also mounted near the operator using extension cables. The transceiver and control
head are mounted using a trunnion or other mounting hardware. If the transceiver is located in a car
trunk, ensure that it is mounted securely and that sufficient cooling is provided. Do not cover the
transceiver with baggage, blankets, and others.
NOTICE: The keypad mic should only be plugged into the Modified Modular Plug (MMP)
connector located on the control head, in either dash mount or remote mount configuration.

1.2.3
Multi Control Head
The multi control head option allows separate, remotely operated control heads to operate and control
the radio.
For example, a fire truck could have a control head located in the cab and on the rear of the truck so
that the radio could be operated from outside the vehicle.
NOTICE: The dual control head can be used together in the future.

1.3
Motorcycle Configurations
The mobile motorcycle radio models provide most of the equipment needed for installing a standard
mobile radio on a motorcycle.
Most of this radio system is standard equipment. See Motorcycle Radio Installation on page 94 for
further information.
NOTICE: The motorcycle configurations are not applicable O9 control heads.

1.4
Base/Control Stations
NOTICE: The base/control station option is not applicable for O9 control heads.

28

MN005720A01-AA
Introduction

The antenna installation must comply with the following requirements if mobile radio equipment is
installed at a fixed location and operated as a control station or as a fixed unit to ensure optimal
performance and compliance with the RF energy exposure limits in the standards and guidelines listed
in the 6881095C99 manual:
• The antenna should be mounted outside the building on the roof or a tower if at all possible.
• As with all fixed site antenna installations, it is the responsibility of the licensee to manage the site in
accordance with applicable regulatory requirements and may require additional compliance actions
such as site survey measurements, signage, and site access restrictions to ensure that exposure
limits are not exceeded.

1.5
Tools Required for Radio Installations
These are the tools required for mobile radio installation.

Table 1: Tools Required for Radio Installations

Tool Part Number
10 mm wrench –
5 mm Allen wrench –
Rubber-coated pliers –
Regular slot screwdriver of Phillips #2 –
Pin removal tool 6680163F01

MN005720A01-AA
Standard Configurations

Standard Configurations
The radio operates only in negative ground electrical systems with a valid operating range of 10.8–16.3
VDC. Before starting the installation, ensure that the ground polarity of the vehicle is correct.
Accidentally reversing the polarity could damage the radio and cause the cable fuses to blow.

2.1
Planning the Installation
Planning is the key to fast, easy radio installation. Before starting the installation, inspect the vehicle
and determine how and where you intend to mount the antenna, radio, and accessories. Plan wire and
cable run to provide maximum protection from pinching, crushing, and overheating.
CAUTION:
Before installing any electrical equipment, check the user manual of the vehicle for warnings or
recommendations.
Authorized servicer or installer should complete the installation of this device. Failure to properly
install the device may result in damage to the device, or improper operation.

2.1.1
Installation Examples
The mobile two-way radio offers various methods of installation, with accessories placed to the vehicle
as desired. The radio can be dash or remote mounted except for the O9 control head, which can only
be mounted remotely.
