8-1 Removing a Cassette When Tape Slack Occurs

If tape slack occurs in the unit, it is necessary to
remove the upper lid and sound baffle. This job
should always be entrusted to a technician who has
undergone service training.

To clean the video heads and audio heads, always use
the special-purpose Sony BCT-5CLN cleaning
cassette.
Follow the instructions with the cleaning cassette
carefully, as inappropriate use of the cleaning cassette
can damage the heads.

To carry out head cleaning, use the following
procedure.

For details, refer to Section 1-16, “How to Take Out the
Cassette When the Tape is Slacking”, in the Installation
Manual.

8-2 Head Cleaning

1

Insert the cleaning cassette.

2

Press the EJECT button and PLAY button
simultaneously.

Head cleaning starts.

3

After a head cleaning operation which lasts for
about 5 seconds, the cleaning cassette is
automatically ejected.

Note

When carrying out head cleaning without using the
automatic cleaning function described above, be sure
to eject the cleaning cassette after use in order not to
damage the heads.
