Error codes F02 and F05 on a Panasonic camcorder typically indicate problems with the tape mechanism or the loading/ejecting system. F02 may indicate an issue with the tape transport mechanism, such as a tape jam or a problem with the tape loading or threading process. F05 could indicate a problem with the reel or spooling mechanism, possibly indicating a fault with the tape movement or tensioning system. It's recommended to consult the user manual or contact Panasonic support for specific troubleshooting steps or to arrange for repairs.
