3. ADJUSTMENTS AND CHECKS

Heading correction at the motion sensor
Heading correction at the motion sensor is done with [Heading Adjust 2] on the [Oth-
ers] menu.
• If the control box is mounted on the hull unit, set the same heading correction as
entered for [Heading Adjust 1] (in [Others] menu).
• If the control box is mounted independent of the hull unit, set the angle measured
from the bow in the clockwise direction. The angle is 0° degrees if the lid of the con-
trol box is directed toward ship’s stern precisely.
• If the motion sensor is a GPS gyro, set 0°.
