CAUTIONS
" appears.
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.
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.
