NAVMAN

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 TRACKER 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 colour scheme for the LCD display. The options are:

Normal

Sunlight:

Brighter colours, more visible in sunlight.

Night:

Reversed colours for night, to preserve night vision.

Map datum
TRACKER 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 TRACKER 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 TRACKER map datum to match the

datum of the paper chart. Then, the latitude and longitude coordinates
of objects displayed on the TRACKER will change to match the
corresponding coordinates on the paper chart.
