Installation Requirements for Compliance with
Radio Frequency (RF) Energy Exposure Safety
Standards
ATTENTION!
This radio is intended for use in occupational/controlled conditions, where users have full knowledge
of their exposure and can exercise control over their exposure to meet FCC limits. This radio device is
NOT authorized for general population, consumer, or any other use.
To ensure compliance to RF Energy Safety Standards:
• Install only Motorola approved antennas and accessories
• Be sure that antenna installation is per “Antenna Installation,” on page 2-33 of this manual
• Be sure that Product Safety and RF Safety Booklet enclosed with this radio is available to the end user
upon completion of the installation of this radio
Before using this product, the operator must be familiar with the RF energy awareness information and
operating instructions in the Product Safety and RF Exposure booklet enclosed with each radio (Motorola
Publication part number 6881095C99) to ensure compliance with Radio Frequency (RF) energy exposure
limits.
For a list of Motorola-approved antennas and other accessories, visit the following web site which lists
approved accessories for your radio model: http://www.motorola.com/governmentandenterprise.

Chapter 1 Introduction
This manual covers the installation procedures for ASTRO APX 7500 mobile and motorcycle radios
with O3, O5 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 and Figure 1-2 show the basic dimensions of the dash mount transceiver trunnion
APX 7500 radio. The transceiver portion of a remote mount APX 7500 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 1-12 is millimeter.
NOTE: The rear accessory connector adds 0.75 in to the overall length. The remote mount length
is 244 mm.
