Maintenance and precautions (Continued)
x If moisture condensation has occurred
None of the functions except cassette
ejection will work. Eject the cassette, turn
off your camcorder, and leave it for about
one hour with the cassette lid open. Your
camcorder can be used again when both of
the following conditions are met:
• The warning message does not appear when the
power is turned on.
• Neither % nor Z flashes when a cassette is
inserted and the video operation buttons are
pressed.
If moisture starts to condense, your
camcorder sometimes cannot detect
condensation. If this happens, the cassette is
sometimes not ejected for 10 seconds after
the cassette lid is opened. This is not a
malfunction. Do not close the cassette lid
until the cassette is ejected.
x Note on moisture condensation
Moisture may condense when you bring
your camcorder from a cold place into a
warm place (or vice versa) or when you use
your camcorder in a humid place as shown
below.
• When you bring your camcorder from a ski
slope into a place warmed up by a heating
device.
• When you bring your camcorder from an air
conditioned car or room into a hot place outside.
• When you use your camcorder after a squall or a
shower.
• When you use your camcorder in a hot and
humid place.
x How to avoid moisture condensation
When you bring your camcorder from a
cold place into a warm place, put your
camcorder in a plastic bag and seal it
tightly. Remove the bag when the air
temperature inside the plastic bag has
reached the surrounding temperature (after
about one hour).

Video head
If you play back a tape recorded in HDV
format, the image and sound may freeze for
a while (about 0.5 seconds).
This occurs if the HDV signals cannot be
recorded or played back correctly because
of dirt on the tape or video head. Depending
on the cassette, this fairly infrequently
occurs even if the cassette is brand new or
is not used a lot.
If this freezing point is created while
playing back, you can solve this problem
and see the pictures by rewinding after
slightly forwarding. Such a freezing point
cannot be recovered if it was created while
recording.
To prevent such a problem, use the Sony
mini DV cassette.
• If the following problem occurs, clean the video
heads for 10 seconds with the Sony DVM-
12CLD cleaning cassette (optional).
