    ComNav 1101 Autopilot HOW AUTOPILOTS WORK 2 - 1 2. How Autopilots Work The purpose of this section is to briefly describe in general terms what an Autopilot does and some of the things you should expect when using an Autopilot with your boat. As well as this section, you must carefully read all the operating instructions in other parts of this manual before operating your autopilot.

    4 - 2 INSTALLATION ComNav 1101 Autopilot Control Head The 1101 Control Head is normally mounted in the vessel’s wheelhouse. It can also be mounted in more exposed locations, such as on a flying bridge. Although the control head is waterproof, it should not be submerged, nor should it be exposed to prolonged direct sunlight.
