Panning
The Pan function enables you to pan the display to view neighbouring
areas by positioning a selected point at the centre of the video circle.
If the current motion mode is Relative Motion (RM) the system
automatically changes the motion mode to True Motion (TM) when Pan is
selected.
Where the current presentation mode is Head Up (Stabilised or
Unstabilised) the system automatically changes the presentation mode to
Course Up (C Up) when Pan is selected.
To pan the picture do the following:
1. Move the cursor to either a specific
point on the chart (for example, a
mariner object or a chart location), or
to a selected position within the
video circle and right click. A semi-
transparent window appears at the
selected point.
2. Select Pan from the window. The selected position is moved to the
centre of the video circle. Own ship and all other chart and target
positions are also moved in accordance.
3. To cancel the operation and remove the window from the screen
select Close Menu .
Panning mode is automatically turned off when the following are selected:
 Off Centre, Centre or Max View
 changing motion mode
 changing presentation mode to Head Up (Stabilised or
Unstabilised)
 Transmit mode
When the system turns panning mode off and the CCRP (radar video origin
if video is displayed) is currently outside the offset limits, the system
automatically centres own ship.
