➤ 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.

Figure 8-10: Radar Set Up Menu

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 8-18).

Display Timing Adjustment

The display timing can be affected by the length of the cable used to connect
the scanner to the display unit. This in turn affects the short range accuracy
shown on the display. If you have extended (or reduced) your inter-unit cable,
you will need to check the display timing before using the system for
navigation.
