operating in Transponder mode an audible chirp should also be heard from the USBL Dunking
Transducer.
Note
The transducers will chirp at the rate determined by the update rate control at
the top of the Navigation display.
If using the integral Heading & Pitch/Roll sensor take hold of the USBL Dunking Transducer
and holding vertically rotate until the yellow line faces North. The Compass Heading indicator
should display approximately 0 degrees. Rotate the USBL Dunking Transducer and check
the Compass Heading indicator follows the rotation.
Finally, hold the USBL Dunking Transducer vertical with the yellow line facing forward and
check the Artificial Horizon indicator display line is horizontal and in the centre of the circle,
then move the head to simulate pitch and roll and check the horizon indicator responds
accordingly.
