Chapter 4: Using the Chart 4-43
Chart Offset
This feature allows you to move the position of the chart in order to correct for position
errors in the cartography. This adjustment is indicated as a distance north/west (+ve)
or south/east (-ve) from your vessel position to a maximum of 1000m. To view the
effects of an offset you can turn the feature on/off. Once calculated, the offset is
applied to all charts. You should therefore adjust/switch off this feature when you enter
a region with different/no chart position errors.
Note:
If your vessel position is not available, the current chart centre is used as the ref-
erence point.
How do I switch on chart offset?
1. Press the MENU button.
2. Select CHART SET UP and then CHART OFFSET from the menu. The OFFSET soft key
is displayed.
3. Toggle OFFSET to ON. ‘Chart Offset’ appears in the top right-hand corner of the
chart application and the SET OFFSET soft key is displayed:
All displayed charts are offset by the currently specified offset value. For details of how
to change this value, please refer to
page 4-44.
