Raymarine 420D manual Dedicated keys, Function bar

Chapter 1: Overview 1-5

The cursor is context-sensitive. Some items on the screen, such as waypoints and chart objects have information associated with them. When you place the cursor over such objects, the information is displayed in the status bar. In addition, a function bar is displayed for certain items. For example, when you place the cursor over a waypoint, the waypoint data is displayed in the status bar and the waypoint options function is displayed.

Dedicated keys

These keys have fixed functions. 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 period of time stated (eg. 3 seconds), then release it.

When you press a dedicated key, one of the following occurs:

1.The associated operation is actioned, eg. change chart scale (RANGE key).

2.A pop-up menu is displayed, providing further options.

3.A set of functions is displayed.

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 set up procedure (see Chapter 4).

Function bar

The function bar at the bottom of the screen contains a number of functions which change according to the current operation. The functions are grouped into related sets and subsets providing access to the various functions. The primary function bar is displayed when you press the ENTER key.

The currently selected function is highlighted by means of a grey background.

When you invoke a function, one of the following occurs:

1.The associated operation is actioned, eg. GOTO WAYPOINT.

2.A sub-set of functions is displayed.

3.A pop-up menu is displayed, providing further options.

4.The appropriate database list (route or waypoint) is displayed.

As with dedicated keys, when you invoke the action, a single audio beep confirms the action. If the selection is not valid for the current screen or mode, three rapid beeps indicate invalid action. If required, you can turn the key beeps off as part of your set up procedure (see Chapter 4).
