Caution
Laser light striking the eye may cause your eyesight to be lost: For safety, be sure to remove any power
supply (AC adapter/charger, battery, etc.) from the DVD video camera/recorder before starting work.
3) Check to see whether the optical pickup is dirty: If it is not dirty, cleaning is not necessary.
If the optical pickup is dirty, use the following procedure to
clean it:
a) Drip one droplet of absolute alcohol on a cotton swab
(*1)
.
Lens cleaner liquid for CD/DVD (generally available) is
also usable in place of absolute alcohol.
b) Use the cotton swab to clean the optical pickup in the
direction of the arrow using just enough force that it
lightly goes down: Using undue force or incorrect
cleaning direction could cause a fault.
*1: Use a cotton swab free from any additive or chemical:
Those made by Jhonson&Jhonson are recommended.
Never reuse a used cotton swab.
