Chapter 3: Operation

3.1 Introduction

This chapter explains how to use the chart functions to navigate with your RayChart 420. It covers the following topics:

•Controlling waypoints; placing, moving, editing and deleting waypoints

•Working with routes; creating a new route, managing routes using the route database and editing routes

•Going to waypoints and following routes

•Changing display modes

•Transferring waypoints and routes

•Using tracks; track set up, showing current track and converting a track to a route (SmartRoute)

•Man Overboard

•Alarms

Safety

The RayChart 420 makes it very easy to mark a waypoint and travel towards it. However, you should always check first that the route is safe. If you are using the chartplotter in combination with an autopilot connected via NMEA, the autopilot will normally prompt for confirmation before it steers the vessel towards the waypoint.

If you have entered your route using a small-scale chart, zoom in to a larger scale to check for hazards, such as small shoals, that may not be shown on the smaller scale charts.

Note: Until you are familiar with interpreting the chart display, you should take every opportunity to compare the displayed objects with visual targets, such as buoys and coastal structures. You should practice harbour and coastal navigation during daylight and in clear weather conditions.

The equipment should not be used as a substitute for good navigational practice.

3.2 Working with waypoints

Introduction

The RayChart 420 enables you to place up to 500 waypoints. A waypoint is a position entered on a chart as a reference or destination point. All waypoints placed on the chartplotter are stored in a waypoint database list which includes symbol, position, bearing, range, date and time.
