APPENDIX F:
CALIBRATIONS
CENTERING CALIBRATION
Note: This procedure is required and is normally only completed once at the time of
the installation. It should also be performed every time the system is transferred to
another boat or after a compass calibration.
1. Power up the system and deploy it using the depth collar to adjust the height so
that the motor can steer without any obstructions.
2. Press the ‘M’ button to enter Manual Mode. Please note that the system is in an
operational mode: Stay a safe distance away from the propeller to avoid injury.
3. Using the left and right arrows (or manually rotating the head of the thruster),
steer the unit so that it is aligned with the keel of the boat (pointing straight ahead
with the propeller facing the stern of the boat).
4. Press and hold the up and down arrow simultaneously for 5 seconds until the
system beeps.
5. The system will return to Manual Mode.
6. To verify that the system has been “centered”, press the off button. The system
will automatically steer to the centered position.
The accuracy of the steering calibration will impact the system’s performance. Care
must be taken to ensure that the thruster is aligned as accurately as possible (ideally
within 1 or 2 degrees) during this calibration.
COMPASS MANUAL CALIBRATION
(Recommended)
Note: Performing a compass calibration procedure is recommended as part of the
installation process to improve the accuracy of the GPS Anchor. It will account
for magnetic errors that can occur if the system is mounted close to other metallic
objects (i.e. cleats, steel fasteners, etc.) which may cause the system functions to
misbehave. This routine performs a similar but more accurate calibration than the
“Compass Auto-Calibration” however it requires an external means of propulsion (i.e.
outboard engine or paddle).
1. The boat must be in the water to perform this calibration. Make sure that there are
no obstructions nearby (docks, pilings, other boats, etc.) and that the water is fairly
calm.
2. Power up the system and deploy it using the depth
collar to adjust the height so that the motor can steer
without any obstructions.
