Chapter: 5. Calibration procedure
Step 1. Heading error correction:
The vessel sails a steady course in calm waters and the user reads the resultant angle (averaged drift).
This is entered into the system using the Head err button and encoder on menu 3, and adjusted until the
averaged drift angle is zero.
Step 2a. Manual speed calibration/adjustment:
The user enters speed values directly into the calibration table by comparing to other equipment, such
as GPS. This can also be used to adjust values. Menu 2 allows you to enter the values directly. Press and
hold an empty button will take the current values and place them in the table.

adjustment.
Placing values in the BT (Bottom
Track) elds are valid. Doing this in
the WT (Water Track) is not accurate.
(Step 2b is recommended).
