Maintenance and
Inspections

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.
When you insert the cleaning cassette, it is
automatically ejected after a cleaning operation
which lasts for about five seconds.
Note
Do not run the cleaning tape more than six times in
succession to avoid damaging the heads.
Refer to the instructions of the cleaning cassette for
detailed information about cleaning the video and
audio heads.

Condensation

If you move the camcorder from a very cold place
to a warm place, or use it in a damp location,
condensation may form on the head drum. If the
camcorder is operated in this state, the tape may
adhere to the drum, causing a failure or even
permanent damage.
Note
Before moving the unit from a cold place to a warm
place, make sure no cassette is loaded in the unit.
When condensation is detected
If the condensation detection mechanism detects
condensation on the head drum during use, a
popup window appears on the display of the
control panel, displaying the message "VTR:
007F HUMID ERROR" (see page 187).
See the figure under "Error Messages Related to the
VTR Module" (page 185) for more information
about this and other error messages.
When condensation is detected, the camera enters tape
protection mode (see page 185).

Maintenance and Inspections

If "VTR: 007F HUMID ERROR" appears
immediately after you power the system on
Leave the system powered on, and wait for the
message to disappear. Cassettes cannot be
inserted while the message is visible.
Even if the VTR has no condensation, moisture
collected on tape may cause the tape to adhere to
the drum, which will damage the tape.
This unit can check whether the drum rotates at
the proper speed when it is started, so that tape
adhesion caused by moisture collected on tapes
can be detected. If tape adhesion is detected
during this process, the error message "SLACK-
50" or "SLACK-51" is displayed. In this case, the
VTR is in tape protection mode (see page 185).
Take out the inserted tape with reference to the
Maintenance Manual and check the tape, for
example, for moisture and adhesion of sticky
substances, or contact a Sony service
representative.
When you suddenly move the VTR from a cold
location to a warm one
Leave the VTR powered off for about 10 minutes,
since some time is needed for the condensation
detection mechanism to work.

Note About the Battery Terminal

The battery terminal of this unit (the connector for
battery packs and AC adaptors) is a consumable
part.
Power may not be supplied to the unit properly if
the pins of the battery terminal are bent or
deformed by shock or vibrations, or if they
become corroded due to prolonged outdoor use.
Periodic inspections are recommended to keep
the unit working properly and to prolong its
usable lifetime.
Contact a Sony service or sales representative for
more information about inspections.
