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 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.
How To Handle A CD-ROM
•Take care not to soil or scratch the mirror surface
(opposite to the printed surface). Do not write
anything or put a sticker on either the front or back
surface. If the CD-ROM gets dirty, gently wipe it
with a soft cloth outward from the centre hole
using a circular motion.
•Do not use conventional disc cleaners or cleaning
spray.
•Do not bend the CD-ROM or touch its mirror
surface.
•Do not store your CD-ROM in a dusty, hot or
humid environment. Keep it away from direct
sunlight.
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.
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 Power Adapter/
Charger, etc.) and wait a few minutes and then re-
connect it and proceed as usual from the
beginning.
