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.
Handling the Optical-Fiber
Connector (When Optional HKSR-
101 Is Installed)
Communications errors can occur if dust accumulates on
the surface of the connector of the optical-fiber cable.
Always clean the optical-fiber connector before use.
Whenever the optical-fiber connector (CAMERA
connector) is not in use, always cover it with the cap
supplied with the HKSR-101 so that no dust accumulates.
Refer to the HKSR-101 Installation Manual for
information about cleaning the optical-fiber connector.

Condensation

If you suddenly move the VTR (SRW-1) from a cold
location to a warm one, or use the VTR in a very humid
place, moisture in the air can collect on the head drum or
tape guide. This is called condensation.
If you play a tape under these conditions, the tape may
adhere to the drum where moisture has collected and
become damaged. To prevent this, the SRW-1 has a
condensation detection mechanism.
When condensation is detected
If the condensation detection mechanism detects
condensation on the head drum during use, a popup
window appears in the display of the control panel,
displaying the message "VTR: 007F HUMID ERROR"
(see page 104).
See the figure under "About Error Messages"(page 104)
for more information about this and other error messages.
When condensation is detected, the VTR enters tape
protection mode (see page 104).
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 104). 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.
