Radar System Checks
and Adjustments
i. Align the vessel’s bow to the target.
ii. Note the position of the target relative to the Heading marker.
iii. If the target is not under the Heading marker, there is an alignment error
and the radar can be adjusted as detailed below.
➤ To adjust the radar to eliminate the alignment error:
1. If a visual relative bearing of a target has been determined, as in 2.1 above,
set an EBL to this relative bearing.
2. Press the
MENU key to display the setup soft keys and select RADAR SET UP.

3. Use the trackpad to move the selection bar on the Radar Set Up Menu to
BEARING ALIGNMENT.
4. Use the soft keys to adjust the Bearing Alignment slider and to rotate the
radar picture. As soon as you start the adjustment, the menu is cleared so
that the rotation of the picture can be seen. The keys can pressed and held,
to rotate the picture quickly, rather than in single steps.
5. Rotate the picture to place the target under the EBL, or Heading Marker,
depending on the method used to obtain the correct relative bearing.
6. When the bearing alignment error has been eliminated press
ENTER to re-
display the Radar Set Up menu.
7. Press
ENTER again to return to the set up soft keys, then press CLEAR to
return to the normal radar screen.
8. After adjusting the radar, always check the bearing alignment at the next
opportunity. Usually the bow alignment to target is the most convenient
method (see If the vessel is under way (in reasonably calm conditions): on
page 8-17).
