1.16 How to Mark MOB Position
Use the MOB (man overboard) feature to mark the position of man overboard on the
display screen. Click the [MOB] button (in any mode) on the InstantAccess bar.
The MOB mark instantly appears at the geographical position of your ship when the
button is clicked.
Up to 100 MOB marks can be saved. When the capacity for MOB marks is reached,
the oldest mark is automatically erased to make room for the latest.
To delete an MOB mark, right-click the mark to show the context-sensitive menu then
select [MOB Delete].
Exercise caution when using this feature in strong tide or current. The person will not
be at the MOB position for a very long time.
1.17 How to Offset Position
The position shown in the Sensor information, datum box (section 1.9) may be differ-
ent from the actual position. This error affects the positioning accuracy of radar ech-
oes, radar map and TT and AIS symbols. If there is a difference, apply an offset to
position as shown below to compensate for the error.
1. Right-click the display area to show the
context-sensitive menu.
2. Select [Own Ship Offset] and push the
left button. The color of the cursor be-
comes blue.
3. Roll the trackball until the cursor is at the "correct position".
4. Push the left button to confirm.
To cancel the offset, show the context-sensitive menu then select [Reset Own Ship
Offset]. The indication [Offset] and the offset values are then erased from the display.
