Dirty heads can cause the following
problems:
... No picture during playback.
... Blocks of noise appear during playback.
... During recording or playback, the Head Clog
Warning indicator “
” appears.
... Recording cannot be performed properly.
In such cases, use an optional cleaning
cassette. Insert it and play back. If the cassette
is used more than once consecutively, damage
to the video heads may result. After the
camcorder plays back for about 20 seconds, it
stops automatically. Also refer to the cleaning
cassette’s instructions.
If, after using the cleaning cassette, the
problems still exist, consult your nearest JVC
dealer.
Mechanical moving parts used to move the
video heads and video tape tend to become
dirty and worn out over time. In order to maintain
a clear picture at all times, periodic check-ups
are recommended after using the unit for about
1,000 hours. For periodic check-ups please
consult your nearest JVC dealer.
Serious malfunctioning
About moisture condensation
●
You have observed that pouring a cold liquid
into a glass will cause drops of water to form on
the glass’ outer surface. This same
phenomenon occurs on the head drum of a
camcorder when it is moved from a cool place
to a warm place, after heating a cold room,
under extremely humid conditions or in a place
directly subjected to the cool air from an air
conditioner.
●
Moisture on the head drum can cause severe
damage to the video tape, and can lead to
internal damage to the camcorder itself.
Appears if condensation occurs. When this
indication is displayed, wait more than 1 hour
until condensation disappears.
CONDENSATION, OPERATION
PAUSED PLEASE WAIT
If malfunctioning occurs, stop using the unit
immediately and consult your local JVC
dealer.
The camcorder is a microcomputer-controlled
device. External noise and interference (from
a TV, a radio, etc.) might prevent it from
functioning properly. In such cases, first
disconnect its power supply unit (battery pack,
AC Adapter, etc.) and wait a few minutes and
then re-connect it and proceed as usual from
the beginning.
