How to display other ARCS charts

How to select a chart from ARCS catalogue
You may use the ARCS Catalogue to display an ARCS format chart.
1. Open the Chart menu.
2. Select Chart Catalogue from the menu.
3. From the ARCS Catalogue dialog box, activate desired chart. For more information, see section 9.11.2 "ARCS
catalogue".
4. Click the Open button.
Indication of availability of alternative charts such as S57 (ENC) or other suitable ARCS
chart
The system has several indications to alert you to availability of charts. The indication is based on information
available from the position of your ship if automatic TM reset is active, or from current position of cursor if
automatic TM reset is off.
•
Larger RNC: More detailed ARCS chart is available.
•
Equal RNC: Same scale ARCS scale is available.
•
Larger ENC: More detailed ARCS chart is available.
•
Equal ENC: Same ENC compilation scale is available.
•
Smaller ENC: Smaller ENC chart is available.
Note: When using ARCS, the system also recognises if ENCs are available over the specified area and indicates it
with the texts shown above. This is important because under the current IMO rules only ENC charts can fully
replace the traditional paper charts.
How to browse your ARCS charts
You may view S57 charts using different positions and different scales. The basic tools for browsing charts are
Range -, Range+, Set Chart Center, ShipOffcenter and TM Reset.
Set Chart Center allows you to look ahead from a place other than own ship's
current position. Select Set Chart Center from the Main menu to display the dialog
box shown right. Use the scrollwheel to set the latitude and longitude position for
chart center then click the Set Center button.
Note: The chart can also be centered (with less precise positioning) by placing the
cursor at desired location, displaying Set Chart Center/Info/Activate Scroll in the
dialog box and pushing the left mouse button.)
To turn off automatic true motion reset, display and click TM Reset (in the guidance area). When true motion reset
is off, the indication "Ship off screen" appears in the information area.
To restore own ship's position to the screen center, display TM Reset/Info/ShipCenter in the mouse functions area
then push the right mouse button.
Range - and Range+ change the chart scale. If true motion reset is active, ZOOM IN and ZOOM OUT keep the
relative position of your ship with respect to the display. If true motion reset is on, ZOOM IN and ZOOM OUT keep
the relative position pointed by the cursor with respect to the display.
The system automatically selects next larger or smaller scale. If a chart with larger compilation scale is available at
your current viewing position, the message "Larger Scale Data Exists" appears.
If the indication "Equal RNC" appears, this means that you have a chart with the same scale and overlapping with
the displayed ARCS chart. When you reach an edge of a chart and the indication "Equal RNC" appears, this means
you can switch to another chart with the same scale to the display by displaying Edit Insert/Info/Select Next in the
mouse functions area and pushing the right mouse button. An overlapping chart with the same scale will be opened.
