Serious malfunctioning
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.
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.
CAUTIONS
(cont.)
5. 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 cassettes 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.
