Head Cleaning

Always use the PDVM-12CL Cleaning Cassette to
clean the video and audio heads. You can run the
cleaning cassette for 10 seconds per cleaning
operation. Follow the instructions for the cleaning
cassette, as inappropriate use of the cleaning cassette
can damage the heads.
To clean the heads
Insert the cleaning cassette. This automatically starts
cleaning. You cannot operate any tape transport
control buttons other than the EJECT button during the
cleaning operation.
After about 10 seconds, the cleaning cassette will be
automatically ejected.
