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 crlnditioner.
• Moisture on the head drum car/cause severe
damage to the video tape, and can lead to
internal damage to the camcorder itself.
Serious malfunctioning
If malfunctioning occurs, stop using the unit
immediately and consult your local JVC dealer.
The camcorder is a micrr)computer-controlled

TV, a radio, etc.) might prevent it from functirln-
ing properly. In such cases, first disconnect its
power supply unit (battery pacl<, AC Charger
Station, etc.) and press tile RESET button and
then re-connect it and proceed as usual from
