Setting the Chart Orientation
The orientation of a chart refers to the relationship between the chart and the
direction that you are travelling in. It is used in conjunction with Relative Motion
mode (see page 89) to control how your boat and chart relate to one another and
how they are displayed on screen. The current chart orientation mode is indicated
in the Status Bar (see page 24).The mode that you choose is restored at power up
and consists of the following:
North Up (N-UP)
In North Up mode, the chart orientation is fixed with true north upwards. As your
heading changes the boat symbol moves accordingly. This is the default mode for
the chart application. When this setting is selected, the indicator ‘North-Up’ or ‘N-
UP’ appears in the Status Bar in white text.
Head Up (H-UP)
Head Up mode displays the chart with your boat’s current compass heading
upwards. This settings requires heading data from an optional compass. As the
heading changes the boat symbol remains fixed and the chart picture rotates
accordingly. As long as heading data is received, the indicator ‘Head-Up’ or ‘H-UP’
appears in the Status Bar in white text. If heading data is lost, the indicator
changes to ‘(Head-Up)’ or ‘(H-UP)’ in amber text.
Note:
To prevent continuous backwards and forwards rotations as the boat yaws from
side-to-side, the chart will not update unless the heading changes by at least 10 degrees
from the last displayed orientation.
