Motorola APX 4000 Guide

MOTOROLA APX PORTABLE RADIO OVERVIEW
While the radios addressed in this guide will be using the Commonwealth of Massachusetts Interoperable
Radio System (CoMIRS), the purpose of this guide is not to instruct the reader on the system itself, but to
explain what the various features of the radios are.
There are four types of portable radios that can utilize the system as it stands today. Two Kenwood Viking
models and two Motorola models. This guide deals with the two Motorola models: the APX 4000 and the
APX 6000 portable radios. The APX 6000 can be upgraded to a multiband radio (APX 8000) but will not be
discussed in this guide. These radios will operate in both the analog and digital modes by simply selecting the
proper zone.
As both radios are from the same APX family, and are programmed as similar as possible, many of the
programable buttons have the same function and are located in a similar location. The APX 6000 has a few
buttons/switches and functions that are not available on the APX 4000 and will be noted.
