As you press a key, a single audio beep confirms the key action. If the
key-press is not valid for the current screen or mode, three rapid beeps
sound to indicate that no response is available. If required, you can turn
the key beeps off as part of your setup procedure (see Chapter 6).
The RayChart 620 includes pop up help to assist you when you start
using the system. When you press a key to perform a task, a prompt is
displayed that provides additional information or instructions. Once you
are familiar with the keys and the way they work, you can switch off the
help to leave the chart display clear.

Text Conventions

Throughout this handbook, the dedicated (labelled) keys are shown in
bold capitals; for example, MENU. The soft (unlabeled) key functions,
menus and options are shown in normal capitals; for example, ROUTE.
Operating procedures, which may consist of a single key-press or a
sequence of numbered steps, are indicated by the
margin.
The short exercises in this chapter are shown in italic type, like this
paragraph.
Terms included in the glossary are shown in bold type.

2.2 Turning the RayChart On and Off

To turn the RayChart on and start operation:
1. Press and release the red POWER key.
The keys light up, and the display shows the last-used chart. Over
this is the RayChart status screen, which includes:
- Software version number
- Database version number
- Card number and description for each of the two card slots, if in
use
After 10 seconds, a notice is displayed reminding you that the
RayChart is only an aid to navigation, and should be used with
appropriate prudence and judgement.
Note: You can now turn on and adjust the display backlighting and
contrast, if required, as described later in this chapter (see
Section 2.5).
