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 POWER
switch is set to OFF (CHG). The pre-
installed rechargeable battery is always
charged while your camcorder is connected
to the wall outlet via the AC Adaptor or
while the battery pack is inserted. The
rechargeable battery will be fully
discharged in about 3 months if you do
not use your camcorder at all without the
AC Adaptor connected or the battery pack
attached. Use your camcorder after
charging the pre-installed rechargeable
battery.
However, even if the pre-installed
rechargeable battery is not charged, the
camcorder operation will not be affected as
long as you are not recording the date.
x Procedures
Connect your camcorder to a wall outlet
using the supplied AC Adaptor, and leave it
with the POWER switch set to OFF (CHG)
for more than 24 hours.
