This document provides an overview of various Motorola radio models and components as well as warranty and service information. It lists Motorola radio models including the GP 328, XTS 5000, and various control heads. It describes what the one year warranty covers for the radios and accessories and how to obtain warranty service. It also outlines what the warranty does not cover, including defects from misuse, accidents, or modifications. The rest of the document describes the components and architecture of the radios, including the front end receiver, power amplifier, RF and VCO boards, control boards, and vocoder boards. It concludes with notes about service aids and anti-static workspaces.
