Chapter 2: Getting Started
2.1 Introduction
This chapter provides information, instructions and simple exercises to
get you started using the RayChart 620. It will help you to become
familiar with the chart display and the functions of the controls before
you start using the RayChart for routine navigation. It also explains how
to change the lighting and how to use chart cards.
More detailed information on operating the RayChart is given in
Chapters 3, 4 and 5.
Basics
The RayChart 620 is controlled using a trackpad and 12 keys. Eight of
the keys are labelled, and are dedicated to specific functions. The
remaining four, at the bottom of the display, are “soft” keys, and are
used to perform different functions in different circumstances. The soft
key functions are indicated by labels or menus displayed at the bottom
of the screen, above each key.
Some keys can be used in two ways:
• Press: Press the key momentarily and then release it. This method is
used for most key operations.
• Press and hold: Press the key and hold it down for the length of time
stated (for example, 3 seconds), and then release it. This method is
only used in special circumstances.
