Using a Cleaning Tape (Commer-
cially Available)
You can clean the video head with a
commercially available cleaning tape.
Notes:
• Excessive use of the cleaning tape may
cause damage to the video heads. Please
read the instructions accompanying the
cleaning tape carefully before using it.
• The fast forward and rewind functions cannot
be used when the cleaning tape is in the
camcorder.
