Introduction
This manual covers the HARDI Controller 5500 and the options it supports like SafeTrack
on the Commander and IntelliTrack on Navigator.
It assumes the reader has knowledge of the more basic HC2500. The menu systems,
calibration and operations of the HC5500 are built up from the HC2500. The sensors used
are also similar or the same.
This manual also at times has notes on the HC6500. This is because the HC6500 is built up
around the HC5500 and has many similarities.
