should show 'HdG0' to indicate that the sensor is no longer
compensated and is ready to be compensated again.
5. If the LCD shows 'HdG0' then it is not compensated, and is ready to
be compensated, so continue with the steps below:
a. Place the vessel in a position where it can be swung through
a full 360 degrees.
b. Align the vessel to approximately 270 degrees. It must not be
at a heading of below 180 degrees.
c. Press both buttons. The LCD will show 'HdG ', and then
after a short time it should change to 'HdGi' to show that the
process has been initiated. If it is desired to stop the process
press both buttons again.
d. Begin swinging the vessel, either by hand or by motoring
circles. The rate of rotation is not critical, but about one
minute per revolution is suitable. The movement should be
smooth, with a minimum of roll and acceleration.
6. During this process the LCD will change to show 'HdGr', indicating
that the calibration process is running.
7. If at any time the LCD shows a number after 'HdG' then an error has
occurred, as below:
'HdG1' = Upon initiating the procedure the heading was
less than 180 degrees, restart the procedure with
a heading of approximately 270 degrees.
'HdG2' = The speed of rotation is too slow, restart the
procedure making sure that the speed of rotation
is faster.
'HdG4' = Memory Error, contact your dealer for advice.
'HdG6' = Battery Voltage is below 11 Volts.
8 If any other number is seen then consult your dealer for advice.
9. After a number of rotations the LCD will change to show 'HdGc',
indicating that the calibration is complete.
10. Return to the main display by pressing the LOCK button three times
to select the Calibration Mode End Screen, and then pressing both
buttons together.
