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.
Built-in Clock’s Rechargeable Lithium Battery
To store the date/time in memory, the clock’s recharge-
able lithium battery is integrated in the camcorder.
While the camcorder is connected to an AC outlet using
the AC Adapter, or while the battery pack attached to
the camcorder continues to supply power, the clock’s
rechargeable lithium battery is always charged.
However, if the camcorder is not used for approx. 3
months, the clock’s lithium battery will become
discharged and the date/time stored in memory will be
lost. When this occurs, first connect the camcorder to
an AC outlet using the AC Adapter for over 24 hours to
charge the clock’s rechargeable lithium battery. Then
perform the date/time setting before using the
camcorder.
Note that the camcorder can be used without setting
the date/time.
