18-10 Changing the PPI position
You can move the PPI (Plan Position Indicator)
centre to a different location if you are in
Relative motion mode. (If you are in True
motion mode, the radar automatically
positions the PPI centre.)
To change the PPI position:
1 From the radar window, press MENU then
select Position.
2 There are three choices:
• Centre. The PPI centre is in the centre
of the radar window so that all other
objects move relative to your boat.
• Look Ahead. The PPI centre is
positioned so that the radar window is
offset from the centre to give you the
maximum view ahead.
• Set. Offset the PPI centre in the radar
window. (This works only when you are
using relative motion (RM) mode). Use
the arrow keys to move the PPI centre
to the new position then press
ENTER
to
confirm. The new position must allow
most of the radar sweep to appear
on the radar window; if it doesn’t, the
PPI centre will be moved as close as
possible to the desired position.
