How to browse your charts

Range -, Range+, Set Chart Center, ShipOffcenter and TM/CU Reset.
Activate Scroll allows you to look ahead from a place other than own ship's current position. Spin the scrollwheel
to display Set Chart Center/Info/Activate Scroll in the mouse functions area. Put the cursor on a desired place on the
chart then push the right mouse button. Keep the button pressed down while moving the cursor to desired place.
Release right button to redraw the chart. You can repeat this operation until you have the desired area on the screen.
When true motion reset is off, the indication "TM Reset off" or "Ship off screen" appears in the information area.
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/CU 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/CU 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 on, ZOOM IN and ZOOM OUT keep the relative
position of the own ship with respect to the display. If true motion reset is off, 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.
