[CA] [CA11] Waypoints erased

[Chuck - Raymarine - Moderator]

Brad,

This is quite unusual. It may be indicative a surge which occurred during the battery swap out. As indicated within the FAQ found here, such surges can be detrimental to the marine electronics. The problem reported may also be indicative of a fault within the software operating within the MFDs ... it is recommended that these MFDs be operating with LightHouse II v19.03 software. Within a network of MFDs, the waypoint, route, and track data is stored within the system's Data Master MFD. Should the system have been started up and someone have inadvertently designated a repeater MFD as the system's Data Master, then this may have also been the cause of data loss. Less likely, but possible, the problem reported may be indicative of a problem with the data itself. Please click here to view a FAQ addressing addressing waypoint constraints. Finally, should the reported problem seem to occur each time that that the MFD's have been switched off for several hours, then it may indicate a problem with the Data Master MFD's memory.
