The position alignment feature functions to fine tune ship's position by using radar, ra-
dar echo target and chart material.

If position alignment is in use, the Alert 640 "Chart Align: Over 30 Min." is generated 
every 30 minutes to remind the user to align position. The alert is automatically erased 
in 10 seconds.

If the radar echo targets' symbols are not positioned correctly on the chart, there is ei-
ther position error or gyro error or some combination of these errors.

Position may be aligned on the ECDIS display by moving own ship position or by mov-

the [Offset] button at the top-right position on the screen, put the cursor on the correct 
position then click. The amount of offset, in bearing and range, appears to the right the 
[Offset] button.

The latitude and longitude position indication is shown in yellow characters when the 
position align feature is active.

Click the [Offset] button to cancel the position offset.
