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.
• If the playback picture does not improve after cleaning the video heads it may indicate a malfunction. Consult a Canon Service Center.

attention:

• Tapes already recorded with dirty video heads may not be played back correctly even after cleaning the video heads.
• Do not use wet type cleaning cassettes as this may damage the camcorder.
