If a stepper or synchro gyro is connected to the autopilot system 
via the GI50 Gyro Interface, a display for the heading 
adjustment is presented at Power On or at change of compass in 
the User Set-up menu. Use the course knob to align the autopilot 
read-out to correspond with the gyro heading. Check the 
alignment every time the autopilot/gyro is switched on. If two 
stepper gyros are connected, both will simultaneously be 
aligned. A stepper gyro used as monitor compass will 
automatically be aligned to the steering compass.
