3. Press

or

to store the new settings and return to the previous
display.
Alternatively, after several the seconds the lighting controls are removed
and the screen returns to the previous display.
The new lighting and contrast levels are retained until you reset them or turn off
the chartplotter.
At power-on, the monochrome screen lighting is always off, but the last-used
contrast setting is retained.
The color screen powers-on at the last used settings for brightness and night/day
view.
2.4 Using Chart Cards
The chartplotter has a built-in world map. Most areas are covered on a scale of
about 300nm per inch on the screen, although some populated areas have
details down to 30nm per inch on the screen. The chartplotter displays a scale
indicator on the screen for all chart displays.
To use the chartplotter fully, charts with detailed information for the area in
which you wish to navigate are required. These are available on C-MAP NT
electronic chart cards (C-Cards), each of which can store as many as 20 charts
in an electronic format. A single C-MAP chart normally provides as much
information as is available in paper charts for that geographic area, with detail
up to 0.05nm per inch.
The chartplotter allows you to install two chart cards at the same time. You can
also use the slots for C-MAP Memory C-Cards, which allow you to store and
retrieve data such as waypoints and routes.
Note: You can insert and remove cards while a chart is displayed. The chart
information is displayed when the chartplotter redraws the screen eg, when you
pan outside the current area or use the
RANGE
key to change the chart scale.
After removal of a card, chart information is retained until screen redraw.
You should not insert or withdraw either card whilst a chart is redrawing.
Inserting a Chart Card
➤
To insert a chart card:
1. Check that the card is the correct format (C-MAP NT C-Card), with the
required chart stored on it.
2. Open the card cover, at the top left of the chartplotter front panel, by
pushing the latch to the left and then opening the cover as shown in the
illustration on the following page.
