CAUTIONS
Please read these cautions before operating the VHS-C Movie.

Video Head Clogging
The video heads are the means by which the VHS-C Movie places
picture signals on the tape during recording, and reads picture
signals from the tape during playback. If these heads become dirty
and clogged from long use, the signals can no longer be recorded
correctly, and the playback picture will be distorted accordingly.
This is the case, for example, during the playback of a tape, the
sound of which is reproduced normally, but no picture is seen, or
the picture is greatly distorted. When such symptoms occur, have
the VHS-C Movie checked by qualified service personnel.
The VHS-C Movie is equipped with head clogging detection
function. When the heads are clogged, the O Indication in the
EVF will appear. As the accumulation of dirt on the heads may be
dislodged by the movement of the tape, it is F>ossible that this
indication sometimes appears, but may not reappear on the next
recording starts.
The head clogging detection function will be activated when the
shooting is started from the recording pause mode. However, it will
not be activated when shooting immediately after replacing the
cassette and after performing Camera Search or Playback.
If Condensation Forms Inside the VHS-C Movie
Condensation (dew) forms when warm air comes in contact with a
cold object, for example on a window in a heated room in winter.
Condensation may form in the VHS-C Movie and damage the tape
and the video heads, if:
•The VHS-C Movie is in a room where the heater has just been
turned on.
•The VHS-C Movie is in a room with steam or high humidity.
•The VHS-C Movie is brought from cold surroundings into a
well-heated room.
•The VHS-C Movie is suddenly brought from cool surroundings,
such as an air-conditioned room or car, to a place which is hot
and humid.
•When condensation has formed inside the VHS-C Movie, the
“DEW" indication in the EVF and the Dew Indication Lamp
located on the panel with the General Operation Controls will both
flash. A few seconds later, the unit will turn itself off to protect the
tape and the video heads.
After a while, turn the unit on again and make sure that the Dew
Mark is not displayed any more. Then, wait about 1 hour before
operating the VHS-C Movie again. Depending on the surrounding
conditions, it may take several hours before the VHS-C Movie
can be used again.
•As condensation forms gradually, it may take about 10-15
minutes before the VHS-C Movie turns itself off after a change of
working environment.
•In an extremely cold place, condensation may freeze and turn
into frost. In this case, it may take quite some time for the frost to
melt, turn Into dew and evaporate.
•When you bring the VHS-C Movie from a very cold place, e.g. the
ski slopes, into a heated room, keep it in a tightly closed plastic
bag or similar to prevent condensation from forming inside the
VHS-C Movie.
Keep the VHS-C Movie away from Oily Smoke and Steam

Surrounding Conditions
Use the VHS-C Movie under conditions where the temperatures
are between 0®C and 40°C, and where the humidity is between
20% and 80%. To avoid deformation of the outer case or other
damage, do not leave it exposed to direct sunlight for any length of
time, also never leave it in a closed automobile.
