Chapter 1 Introduction

This manual covers the installation procedures for ASTRO APX 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

1.1.1 Dimensions

Figure 1-1, Figure 1-2, Figure 1-3 and Figure 1-4 show the basic dimensions of the dash mount

transceiver trunnion APX mobile radio. The transceiver portion of a remote mount APX mobile is
sized similarly.

When installing the radio, make sure to plan the installation carefully and leave additional room in the
rear of the radio for cabling and accessory connections; in the front of the radio for access, controls,
and cabling (if remote mount); and to the sides of the radio so that you may access and install the
trunnion screws/wing screws.

NOTE: The measurement unit used in Figure 1-1 to Figure 1-22 is millimeter.

Introduction Standard Configurations 1-5

1.2 Standard Configurations

1.2.1 Dash Mount Configuration

NOTE: The dash mount configuration is not applicable for 100W radios and O9 control heads.

There are two versions of the APX 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 via a coiled cable, which is plugged into the CAN connector on
the transceiver.

Electrical connection between the two takes place within the radio via 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, etc.

NOTE: 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.
