1.5 Cartridges
The GPS Chart400 contains an inbuilt world wide chart. This is suitable for locating countries and
regions within countries, but for details of local regions C-MAP NT chart cartridges must be purchased.
The cartridges are inserted into the receptacle in the upper left corner of the display head. The
receptacle is accessed by removing the protection cover. This cover must be replaced after the chart
has been inserted.
Cartridges are inserted with the label facing forward. Ensure that the edge with the gold contacts, on
the rear of the cartridge, enters the receptacle first. The receptacle is keyed to prevent incorrect
insertion.
