About dirty heads
If video heads (the parts that closely contact
with the tape) become dirty, normal recording
and playback are not properly performed.
Clean the heads with the digital video head
cleaner.
≥Insert the head cleaner into the Camcorder, set
it to the Tape Playback Mode, and play it back
for about 10 to 20 seconds. (If you do not stop
the playback, it automatically stops about
30 seconds later.)
≥We recommend cleaning the heads periodically.
If the heads become dirty, "NEED HEAD
CLEANING" appears during recording. During
playback, moreover, the following symptoms
appear.
≥Mosaic-like noise appears partially or the
sound is interrupted.
≥Black or blue mosaic-like horizontal stripes
appear.
When normal playback cannot be performed
even after the head cleaning
One possible cause is that normal recording
could not be performed because the heads were
dirty at the time of recording. Clean the heads,
and perform recording and playback again. If
normal playback can be performed, the heads are
clean. Before an important recording, be sure to
conduct a test recording to make sure that normal
recording can be performed.
≥If the heads become dirty soon after cleaning,
the problem may be the tape. If so, try another
cassette.
≥During playback, the picture or sound may be
interrupted momentarily, but this is not a
malfunction of the Camcorder. (One possible
cause is that the playback is interrupted by dirt
or dust that momentarily adheres to the heads.)

About the Camcorder
≥When the Camcorder is used for a long time,
the Camcorder body becomes warm, but this is
not a malfunction.
Keep the Camcorder away from magnetized
equipment such as a cellular phones,
microwave ovens, TVs, and video game
equipment.
≥If you use the Camcorder on or near a TV,
images or sounds may be disturbed due to
electromagnetic wave radiation.
≥Recordings on the tape may be damaged, or
images may be distorted, by strong magnetic
fields created by speakers or large motors.
≥Electromagnetic wave radiation generated by
digital circuits including microprocessor may
adversely affect the Camcorder, causing the
disturbance of images and sounds.
≥If the Camcorder is affected by such equipment
and does not function properly, turn off the
Camcorder power and detach the battery or AC
adaptor. Then, connect the battery or AC
adaptor again and turn on the Camcorder
power.
Do not use your Camcorder near radio
transmitters or high-voltage cables.
≥If you record pictures near radio transmitters or
high-voltage cables, recorded images or sounds
may be adversely affected.
Do not spray insecticides or volatile
chemicals onto the Camcorder.
≥If the Camcorder is sprayed with such
chemicals, the Camcorder body may become
deformed and the surface finish may peel off.
≥Do not keep rubber or plastic products in
contact with the Camcorder for a long time.
When you use your Camcorder in a sandy or
dusty place such as on a beach, do not let
sand or fine dust get into the body and
terminals of the Camcorder. Also, protect the
Camcorder from getting wet.
≥Sand or dust may damage the Camcorder or
cassette. (Care should be taken when inserting
and removing a cassette.)
≥If sea water splashes onto the Camcorder, wet
a soft cloth with tap water, wring it well, and use
it to wipe the Camcorder body carefully. Then,
wipe it again thoroughly with a soft dry cloth.
While carrying the Camcorder, do not drop or
bump it.
≥A strong impact on the Camcorder may break its
housing, causing it to malfunction.
