To ensure normal recording and clear pictures, clean the video heads. The video head
may be dirty when:

•playback pictures do not move.
•playback pictures do not appear.
•the x indicator and “
CLEANING CASSETTE” message appear one after another
or the x indicator flashes on the screen during recording.
If the above problem, [a], [b] or [c] occurs, clean the video heads for 10 seconds with
the Sony DVM-12CLD cleaning cassette (optional). Check the picture and if the above
problem persists, repeat cleaning.
If the video heads get dirtier, the entire screen becomes blue [c].
Cleaning the LCD screen
If fingerprints or dust make the LCD screen dirty, we recommend using a LCD
Cleaning Kit (optional) to clean the LCD screen.
Charging the built-in rechargeable battery in your camcorder
Your camcorder is supplied with a built-in rechargeable battery installed so as to retain
the date and time, etc., regardless of the setting of the POWER switch. The built-in
rechargeable battery is always charged as long as you are using your camcorder. The
battery, however, will get discharged gradually if you do not use your camcorder. It
will be completely discharged in about 4 months if you do not use your camcorder at
all. Even if the built-in rechargeable battery is not charged, it will not affect the
camcorder operation. To retain the date and time, etc., charge the battery if the battery
is discharged.
Charging the built-in rechargeable battery:
•Connect your camcorder to house current using the AC power adaptor supplied with
your camcorder, and leave your camcorder with the POWER switch turned off for
more than 24 hours.
•Or install the fully charged battery pack in your camcorder, and leave your camcorder
with the POWER switch turned off for more than 24 hours.
