Cleaning The Video Heads - Canon optura50 Instruction Manual

Cleaning the Video Heads

When the message "HEADS DIRTY, USE CLEANING CASSETTE" appears, or when the
playback picture becomes distorted, 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.
Do not use wet type cleaning cassettes as this may damage the camcorder.
Tapes already recorded with dirty video heads may not be played back correctly
even when you clean the video heads.
