● 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.
● 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 Adapter, etc.) and wait a few minutes and 
then re-connect it and proceed as usual from 
the beginning.
