INTRODUCTION

How to Use the Reference Guide

This reference guide is designed to assist you in using the DIAD. It is broken into several

sections, reflecting the DIAD menus. In general, the sections are arranged according to the

order of events followed by a typical driver on a typical day. The events you will encounter

earlier and most frequently are covered first.

The Table of Contents shows you where particular sections begin, and graphics indicate quick

reference pages. These step-by-step instructions will show you how to complete a common

activity.

To find information on a particular topic, you can also check the index in the back of the book.

radio link built into the DIAD.
