Note
• If the error messages except the indication "d" are displayed, turn OFF the unit immediately and disconnect the
power cord from the mains to prevent the unit from serious damage before contacting your authorized service
personnel.
In case of dew detection
When condensation (dew, so-called sweating) forms inside the unit, the error message "d" will be displayed on the counter and
all the operation buttons are made inoperative. Leave the unit on and let it remain at room temperature until "d" disappears.
Depending on the surrounding condition, this may take several hours.
Cause of condensation
Condensation forms if warm air comes in contact with a cold object, for example on a window in a well-heated room in winter.
may form if the unit or the video cassette is exposed to sudden changes in temperature and humidity such as may occur when
the unit or the video cassette is taken from a cold to a warm place. For instance:
• In a room where the heater has just been turned on in winter;
• In a room with steam or high humidity;
• If the unit or the cassette is brought from cold surroundings into a well-heated room
Moisture condensation normally occurs gradually. Therefore, there may be cases in which the
"d" indicator does not start flashing until 10 or 15 minutes after moisture has begun to
condense. In particular, if the temperature or humidity in the room change, wait about 20
minutes before using the unit.
