OPERATION
The compass system is activated by switching on the power supply. The compass automatically
compensates for changes in the strength of the earth's magnetic field after calibration. The Super
Halcyon 3 works in both the northern and southern hemispheres without modification. (See section 5
on automatic calibration).
All outputs are protected against accidental short circuit In the event of a short circuit, the compass will
switch off. To return to normal operation, first remove the cause of the short circuit, switch off the
power to the compass, wait a few seconds and then re-apply the power. The compass will then work
normally.
The heading may be seen on the analogue display (compass repeater) or in digital form through the
Hercules system.
