■ Video Head Clogging and Remedy
When the video heads (which contact the tape) are dirty, the
playback picture contains mosaic-like patterns or the whole
screen becomes black. If they become even more dirty, the
recording performance deteriorates and in the worst case,
recording may not be possible at all.
Causes of Dirty Video Heads
•A lot of dust in the air
•High-temperature and high-humidity environment
• Damaged tape
• Long-time use
Using the Minl-DV Format Digital Video Head Cleaner
1 Insert the Head Cleaner into the Movie Camera in the
same way as a video cassette.
2 Press the Play Button [►], and after approximately
20 seconds press the Stop Button [■]. (Do not rewind
the tape.)
3 Take out the Head Cleaner. Insert a video cassette,
perform recording and then play it back to check the
picture.
4 If the picture is still not clear, repeat above operation
steps 1 -3. (Do not use the Head Cleaner more than
3 times in succession.)
Notes:
• Do not rewind the tape in the Head Cleaner after every use.
Rewind it only after the tape has reached its end, and then
use it again in the same way from the beginning.
• If the video heads again become clogged with dirt soon after
cleaning, this might be caused by a damaged tape. In this
case, stop using that cassette immediately.
• Be careful not to clean the video heads too much. (Too much
cleaning could cause excessive wear to the video heads. If
the video heads get worn, the picture is not played back
clearly even after cleaning.)
• If using the Head Cleaner does not clear the video head
clogging, the Movie Camera requires cleaning or repairing by
a service centre.
Please consult with your dealer.
•This Video Head Cleaner is available from service centres.
Periodic Inspection
To ensure optimum picture quality, we recommend that you
have worn-out parts such as video heads replaced after
approximately 1000 hours of use. (However, this depends
considerably on the conditions of use such as temperature,
humidity and dust.)
