On charging the pre-installed
rechargeable battery
Your camcorder has a pre-installed
rechargeable battery to retain the date,
time, and other settings even when the
LCD screen is closed. The pre-installed
rechargeable battery is always charged
while your camcorder is connected to the
wall outlet (wall socket) via the AC Adaptor
or while the battery pack is attached. The
rechargeable battery will be fully discharged
in about 3 months if you do not use your
camcorder at all. Charge the pre-installed
rechargeable battery before you start using
your camcorder.
However, even if the pre-installed
rechargeable battery is not charged, the
camcorder operation other than date
recording will not be affected.
How to charge the pre-installed
rechargeable battery
Connect your camcorder to a wall outlet
(wall socket) using the supplied AC
Adaptor or attach the fully charged battery
pack, and leave it with the LCD screen
closed for more than 24 hours.
