Autopilot looses calibration?

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum wmcunninghamii,

It is recommended that you identify the versions of software which are installed within the ACU-200, EV-1 Sensor Core, and p70/p70R Autopilot Control Head. This information may be obtained via the autopilot control head (MENU->SET-UP->DIAGNOSTICS->ABOUT SYSTEM). Should any of the autopilot components not be operating with the latest available Raymarine product software update, then it would be recommended that the update(s) be performed. Updating the Evolution Autopilot's software will necessitate that a Pilot Factory Reset (MENU->SET-UP->AUTOPILOT CALIBRATION->COMMISSIONING->PILOT FACTORY RESET) be performed, followed by the Dockside Wizard. The Evolution software update and subsequent Pilot Factory Reset will cause deviation data stored within the autopilot to be deleted, necessitating that the autopilot once again create its deviation table and report the maximum detected deviation.

If updating the autopilot's software, it is recommended that the ACU-100's software be updated as well should it not presently have the latest software installed.

Should the problem persist thereafter, then it would be recommended that the ACU-200 be sent to Raymarine’s Product Repair Center to be bench checked / serviced.
