Checking the Chartplotter Operation
To confirm that your chartplotter is operating correctly, perform the following
checks:
1. Without a Navionics Microchart ® card fitted, verify that the world map is
visible.
2. Press the trackpad left/right, up/down and check cursor movement and
normal scrolling action.
3. Insert a Navionics Microchart ® card for the area of your vessel.
Use the RANGE key to zoom-in to check that the new chart cartridge is
being displayed.
4. Ensure that position data is available; use the FIND SHIP function to check
that the cursor is fixed on the vessel symbol which is correctly positioned
at the centre of the chart display, see Chapter 3, Operation.
