Condensation
If you move the unit suddenly from a cold to warm
location, or if you use it in a very humid place,
moisture from the air may condense on the head drum.
This is called condensation, and if a tape is run in this
state, the tape may stick to the drum and can be easily
damaged. To lessen the risk of this occurring, this unit
is equipped with a condensation detection system.
If condensation occurs while the unit is
operating:
The alarm message “MOISTURE HAS BEEN
DETECTED.” appears on the monitor screen, and the
alarm message “HUMID!” in the sub LCD. At the
same time the unit ejects the cassette automatically. If
this happens, leave the unit’s power on and wait until
the alarm messages disappear.
If the condensation alarm messages appear
immediately after powering on:
Leave the unit powered on and wait until the alarm
messages disappear. You cannot load a cassette into
the unit while the alarm messages are being displayed
Once the alarm messages disappear, the unit is ready
for use.
Head Cleaning
Always use the DVM12CL (mini-size) or DV12CL
(standard size) 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.
