3.2 Heading Adjustment
When the BOW mark on the flange of the hull unit cannot be directed toward ship’s bow, adjust the heading so an echo which is dead ahead appears dead ahead on the display.
1.Referring to the previous section, set the TX (transmission) to ON.
2.Locate a target in the bow direction (buoy, for example) and display it on a near range. If the target appears at 12 o’clock the heading alignment is correct. If it does not, measure the error and go to step 2.
Buoy | If target's |
|
position is right of ship's bow for example, heading is skewed left.
