Head Cleaning
Use the BCT-HD12CL Cleaning Cassette to clean the
video and audio heads.  Read the instructions included
with the cleaning cassette carefully, as improper usage
can damage the heads.
Follow the procedure below to clean the heads.
Insert the cleaning cassette.
The tape runs at normal playback speed for about 3
seconds as it cleans the heads.  The cleaning cassette is
automatically ejected when the head cleaning finishes.
Note
Do not run the cleaning tape more than 6 times in
succession to avoid damaging the heads.
Please refer to the supplied Maintenance Manual on
cleaning the video and audio heads.
Moisture Condensation
If you suddenly move the VTR from a cold location to
a warm one, or use the VTR in a very humid place,
moisture in the air can form on the head-drum or tape
guide.  This is called moisture condensation.  If you
play a tape under these conditions, the tape may adhere
to the drum where moisture has collected and become
damaged.
If moisture condenses on the head-drum while you are
operating the VTR, the error message “ERROR-10”
appears in the time data display section.
When moisture condensation has occurred
When this error message appears, the VTR enters the
protection mode and certain operations become
inoperable.
Once the moisture has evaporated, the error message
disappears and the VTR becomes normal.
Please refer to the supplied Maintenance Manual on
protection mode.
If “ERROR-10” appears immediately after
turning the VTR on
Leave the VTR turned on and wait until the error
message goes off.  Inserting a cassette is not possible
while the message is on.
When the error message disappears, you can use the
VTR.
If you move the VTR from a cold to a warm
location
Leave the VTR turned off for about ten minutes since
some time is needed for the condensation-detection
mechanism to work.
