3.4 How to Adjust the Heading
Heading correction at the hull unit
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. Enable transmission as shown in section 3.2.
2. Find a target in the bow direction (buoy, for example) and display it on a near
range perfectly. If the target appears at 12 o’clock the heading alignment is cor-
rect. If it does not, measure the error and go to next step.
3. If the heading is skewed, measure the skew angle.
4. While pressing and holding down the MENU/ESC key, press F1, F3, and F5 key
in order to show the [System] menu.
5. Select [Others] then push the left-click button.
6. Select [Heading Adjust 1] then left-click.
7. Rotate the scrollwheel to enter the angle measured at step 3. The setting range is
-180° to 179°, in one-degree increments.
8. Select [Quit] then push the left-click button.
9. Select Quit on the topmost menu then push the left-click button.
If target's on-screen
position is right of ship's
bow, for example, heading
is skewed left.
