Video Heads
When the message “HEADS DIRTY, USE CLEANING CASSETTE” appears, when the playback
picture becomes distorted, or if, when playing back a tape 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.
Tapes already recorded with dirty video heads may not be played back correctly even when you clean
the video heads.
Do not use wet type cleaning cassettes as this may damage the camcorder.
If the playback picture does not improve after cleaning the video heads it may indicate a malfunction.
Consult a Canon Service Center.
