When the message "HEADS DIRTY, USE CLEANING CASSETTE " appears, when the playback picture becomes distorted, or if during playback of a tape recorded in HDV standard the picture and/or sound stops momentarily (about 0.5 seconds) the video heads need to be cleaned. To maintain the best picture quality, we recommend cleaning the video heads frequently with the Canon DVM-CL Digital Video Head Cleaning Cassette or a commercially available dry cleaning cassette.
To protect your recordings from accidental erasure, slide the tab on the cassette to the left. (This switch position is usually labeled SAVE or ERASE OFF.)
