The trackpad has several functions:
• To move the cursor around the chart screen.
• To select an item from a pop-up menu or database list.
• To adjust a control setting.
• To enter names in database lists .
Press the corresponding edge of the trackpad to move the cursor horizontally,
vertically or diagonally; the longer you press, the faster the cursor moves. The
current cursor position is shown in the status bar at the top of the screen.
Note: During many operations you cannot move the cursor around the screen,
eg. whilst a function bar is displayed, the cursor is used exclusively for
selection.
The cursor is used to:
• Select a position on the chart.
• Select, access and, if valid, move an item, eg. a waypoint, on the chart.
• Pan the chart display.
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).
1-6
RayChart 420/420D Chartplotter
Pop-up menus
Pop-up menus usually provide various options. When a pop-up menu is
on-screen, a set of associated functions is also displayed.
Use the trackpad to select an option from the menu, then use the appropriate
function to set the option, eg. you can specify the radius of the waypoint arrival
alarm and you can set selected navigation data on/off.
Database lists
The waypoints and routes that you create on the chartplotter are stored in
database lists. You can view these lists and select items for editing.
As with pop-up menus, when a database list is on-screen, a set of associated soft
keys is also displayed; use the trackpad to select an item from the list, then use
the appropriate function to edit the item, eg. you can erase a waypoint or a route.
Chapter 2: Getting Started 2-1
Chapter 2: Getting started
2.1 Introduction
This chapter provides information, instructions and a simple exercise to allow
you to practice using the RayChart 420 Chartplotter. It is intended to help you
become familiar with the controls before you start using the chartplotter for
routine navigation.
Note: There is often more than one method of performing a particular task.
Normal operating procedures are detailed in Chapter 3. When you become
familiar with the system you can adapt these procedures to suit your method of
operation.
Conventions used
Throughout this handbook, the dedicated (labelled) keys are shown in bold
capitals; for example, ENTER. The functions and options are shown in normal
capitals, eg. LIGHT.
Operating procedures, which may consist of a single key-press, or a sequence of
numbered steps, are indicated by a ä symbol in the margin.
When textual data is displayed on screen, any unavailable data is shown as
dashes, one per character.
Where procedures refer to Select, this implies using the trackpad to highlight a
function, then pressing the ENTER key to action that function.
Simulator
The Chartplotter display unit includes a simulator mode, which allows you to
practice operating your chartplotter without data from a GPS system. You will
need to use the set up options to switch the display to simulator mode, as
described in Section 2.2, Switching on/off. You can use it in either of two ways:
• Before the chartplotter has been installed on your vessel. In this case, you
only need to connect the Chartplotter display unit to a 12V dc power supply,
fused at 1A, connecting the red core from the power lead to positive (+) and
the black core to negative (-); see Chapter 5 for full details.
• After the chartplotter has been installed on your vessel, but while in the
marina or at anchor.
2-2
2.2 Switching on/off
This section explains how to switch the chartplotter on and off.
ä
To turn the chartplotter display unit on, press the POWER key. The keys light
up, the display unit beeps and the RayChart logo is displayed, followed by the
following warning:
RayChart 420/420D Chartplotter
WARNING
THE ELECTRONIC CHART IS AN AID TO
NAVIGATION DESIGNED TO FACILITATE
THE USE OF AUTHORISED GOVERNMENT
CHARTS, NOT TO REPLACE THEM. ONLY
OFFICIAL GOVERNMENT CHARTS AND
NOTICES TO MARINERS CONTAIN ALL
INFORMATION NEEDED FOR THE SAFETY
OF NAVIGATION AND, AS ALWAYS, THE
CAPTAIN IS RESPONSIBLE FOR THEIR
PROPER USE.
Press “ENTER” to continue.
When you have read and understood the warning, press the ENTER key. The
chart is displayed.
If this is the first time that the chartplotter has been switched on, and no chart
card is installed, the display shows the small-scale world map at Lat 0°/Lon 0°.
Otherwise, the display shows the selected chart area and any data that were
displayed when the display unit was last used.
ä
To turn the display unit off, press and hold the POWER key for at least 3 seconds. A countdown timer is displayed; when it reaches zero the display and key
back-lights extinguish.
Changing the lighting and contrast
You can change the level of backlighting and contrast for the screen. The key
backlighting remains on to enable the keys to be seen at all times.
ä
To change the lighting and contrast:
1. Press the POWER key to display the lighting controls:
Chapter 2: Getting Started 2-3
The last-used control is highlighted in inverse video.
2. Press the trackpad left/right to select the LIGHTS function.
3. Press the trackpad top/bottom to increase or decrease the lighting to one of
four levels. You can press and hold the trackpad to change the setting more
rapidly. The lighting level is adjusted as you change the setting.
4. Press the trackpad right to select the contrast control. There are 16 contrast
levels. Adjust the setting in the same way as for lighting to select the best
level.
5. Press CLEAR to return to the chart screen, with the new lighting and
contrast levels retained.
When the display unit is switched on, screen lighting is restored to ON if it was
ON previously. Whilst the unit is switched on, the chosen lighting level is
retained until you reset it. The new contrast level is retained until you reset it,
even after power-off, unless you set the control very low or very high; in this
case, the contrast will be restored on power-up as follows:
Contrast set < 30% restored to 30%
Contrast set > 70 % restored to 70%
2.3 Chart simulator
When simulator mode is started, your initial simulated position is wherever the
cursor was last positioned. To practice using the chartplotter in a particular
chart area, use the trackpad to pan to that area, then switch simulator ON.
Note: If real position data is available (via GPS or dGPS) and the simulator is
active, simulated data takes precedence. On power-up the simulator defaults to
its previous setting on power-down. Care should be taken to determine
desired mode on power-up. Simulated data should never be used for
navigational purposes.
ä
To view a chart image using simulated data:
1. Press the PAGE key to display the SET UP function bar:
2-4
2. Press trackpad left/right to highlight SYSTEM SET UP and press ENTER
to display the System Set Up menu.
3. Use trackpad up/down to highlight the SIMULATOR option .
4. Use trackpad left/right to select ON.
5. If necessary, use trackpad up/down to highlight, in turn, the SIMULATED
SOG and COG options and trackpad left/right to set as required . These set
Speed in 1Kt intervals and Course in 1° intervals, respectively.
6. Press CLEAR twice to return to the chart screen.
2.4 Controlling the display
This section describes how to:
• Change the display mode.
• Move around the chart by panning the display, changing the chart centre and
changing the chart scale.

Moving around the chart
You will normally operate the chartplotter with the chart showing your vessel’s
current location.
In the default North-Up orientation, the vessel moves in relation to the screen.
You will need to reposition the chart if your vessel moves out of the area
currently displayed, or if you wish to examine or place waypoints in another
area.
Alternatively, you can home the cursor onto the vessel using the FIND SHIP
function. ‘Homing’ locks the vessel to the cursor and updates the display such
that the chart is re-drawn so as to ensure that the vessel is always on screen, see
Using FIND SHIP below.
There are three ways in which you can reposition the chart:
• Use the trackpad to move the cursor to the edge of the chart; the chart pans
across. This method is useful if the area you wish to see is just off screen.
• Automatically re-centre the vessel using the FIND SHIP function.
• Change the chart scale using the RANGE key to zoom out and in to a new
area. This method is useful if the area you wish to see is some distance away.
Using FIND SHIP
FIND SHIP is used to re-draw the chart with the vessel normally at its centre
and the cursor homed on the vessel.
ä
To centre the vessel:
1. From chart mode, press ENTER; the primary function bar is displayed:
Select FIND SHIP; the following actions are performed:
• The chart is re-drawn with the vessel’s position in the centre.
• The cursor is homed onto the vessel position and moves with it.
• When the vessel moves near the edge of the chart window, the chart is
redrawn with the vessel at the centre and the cursor homed on the vessel.
• Whilst homed, the status bar indicates vessel position, SOG and COG.
• If Screen Amplifier is enabled, the vessel is positioned so as to increase
screen forward visibility, see Chapter 4, Setting Up the Chartplotter.
ä
To release the cursor from homed mode press the trackpad to move the cursor
away from the vessel’s current position. The status bar shows the cursor
position, range and bearing.

Changing the chart scale
The RANGE key allows you to change the chart scale so that you can see a
smaller or larger area on the screen.
Plotter mode is available to allow you to zoom into a smaller area, even when no
chart data is available for that scale. To enable plotter mode, see Chapter 4,
Setting Up the Chartplotter.
You can change the chart scale for two purposes:
• To see either more detail (of a smaller area) or a larger area (in less detail) .
• To move the display to another area of the chart, by zooming out to a small
scale chart, then zooming in on another position.
Each time you press the RANGE key, the chart scale changes to the next
available setting. The Status Bar at the top of the screen indicates the distance,
from top to bottom of the display, in nautical miles.

For rapid scale change, press and hold the required arrow on the RANGE key.
The distance indicator at the left-hand end of the status bar is updated whenever
you change the chart scale.
ä
To zoom in to a larger-scale (more detailed) chart:
1. Use the trackpad to position the cursor in the area you wish to see in more
detail and press the bottom of the RANGE key to zoom into the area.
The section of the chart around the cursor is enlarged to fill the screen with
a larger-scale chart showing more detail. The cursor is now positioned in
the centre of the screen.
The distance indicated at the top left of the screen is updated.
3. If further chart enlargement is available using the current chart card you can
press the bottom of the RANGE key to zoom in again, repositioning the
cursor first if required.
An area of further chart detail is indicated by a box around the area as
shown in the following illustration.

4. If no further chart detail is available then, when you press the bottom of the
RANGE key, the result depends upon whether Plotter Mode is on or off :
• If Plotter Mode is Off, the unit beeps three times and the chart scale remains
unchanged, indicating the smallest chart scale is displayed.
• If Plotter Mode is On, the scale is decreased. The vessel, waypoints, routes
and tracklines are displayed without cartography.
The chart information is restored when you return to a chart scale for which the
information is available.
ä
To zoom out to a smaller-scale (less detailed) chart, press the top of the
RANGE key as many times as required.
2.5 Using Navionics Nav-Chart cards
The chartplotter has a built-in world map that can be used for route planning.
Most areas (these are shown with chart box boundaries) are covered at a range
of approximately 64nm as shown on the Status Bar at the top of the screen.
Note: To ensure maximum detail for the built-in world map, two versions are
available covering the Americas and the Rest of the World.
To use the chartplotter as a navigation aid, charts with detailed information for
the area you wish to navigate are required. The charts are available on
Navionics Nav-Chart cards, each of which can store as many as 20 charts in an
electronic format, depending upon its memory storage capacity.
A Nav-Chart card provides an appropriate level of detail for a given geographic
area and scale; this data can be displayed down to a range of
(height) if the data is available.
