Press once or more until the Setup menu is displayed, then select Chart:
Rotation
The options for chart rotation are:
North up: North is always at the top of the chart display.
Track up: The chart is rotated so that the boat direction is to the
top of the display. This option is useful for navigating narrow harbours
or rivers. The EXPLORER asks for a course deviation; this is how much
the boat direction needs to change to make the chart redraw.
Tip: If the chart redraws too frequently, increase the course deviation
setting.
Course up: This option is only available if the boat is navigating
to a destination. The chart is rotated so that the plotted course to the
destination is vertical.
Palette
Select the color scheme for the LCD display. The options are:
Normal
Sunlight: Brighter colors, more visible in sunlight.
Night: Reversed colors for night, to preserve night vision.
Map datum
EXPLORER GPS positions are based on a worldwide reference (datum)
known as WGS 84. Most paper charts are based on WGS 84. However,
some paper charts are based on other datums In these cases, the latitude
and longitude coordinates of objects on the EXPLORER chart display are
different to the latitude and longitude coordinates of these objects on the
paper chart. This applies to all objects, such as the boat, waypoints, tracks,
lines of latitude and longitude and cartographic features such as land,
rocks, buoys and depth contours.
Use Map datum to select the EXPLORER map datum to match the
datum of the paper chart. Then, the latitude and longitude coordinates
of objects displayed on the EXPLORER will change to match the
corresponding coordinates on the paper chart.
