Gently press the cleaning paper to
fix with your finger, and rotate the
upper drum to clean.
Move to and from 5 times for each head.
(Do not move the cleaning paper.)

Rotate the upper drum
with one hand.

Video head cleaning procedure
1. Apply one drop of cleaning liquid to the cleaning paper with the baby oiler.
2. Gently press the cleaning paper against the video head to fix your finger, and move the upper drum so that each head

is passed to and from 5 times (do not move the cleaning paper).

3. Wipe with the dry cleaning paper.

Notes :
• Use the commercially available ethanol of Class 1 as

cleaning liquid.

• Since the video head may be damaged, do not move up

and down the cleaning paper.

• Whenever the video head is cleaned, replace the clean-

ing paper.

• Do not apply this procedure for the parts other than the

video head.
