Maintenance and precautions (Continued)
– Put the battery pack in a pocket to warm it up,
and install it in your camcorder right before
you start taking shots.
• Make sure to turn off the camcorder when you
are not recording or playing back. The battery
pack is also consumed when your camcorder is
in recording standby or playback pause.
• Have spare battery packs ready for 2 or 3 times
the expected recording time, and make trial
recordings before making the actual recording.
• Do not expose the battery pack to water. The
battery pack is not water resistant.
About the remaining battery indicator
• Check the level with the following indicators
and % displayed on the LCD screen.

• The displayed level may not be correct under
certain circumstances.
• When the power goes off even though the
remaining battery percent indicator indicates
that the battery pack has enough power to
operate, charge the battery pack fully again.
Remaining battery percent will be indicated
correctly. Note, however, that the battery
indication will not be restored if it is used in
high temperatures for a long time, or if left in a
fully charged state, or when the battery pack is
frequently used. Use the remaining battery
percent indication as a rough guide only.
About storage of the battery pack
• If the battery pack is not used for a long time,
fully charge the battery pack and use it up on
your camcorder once a year to maintain proper
function. To store the battery pack, remove it
from your camcorder and put it in a dry, cool
place.
• To discharge the battery pack on your
camcorder completely, leave your camcorder in
recording standby until the power goes off.

About battery life
• Battery capacity decreases over time and
through repeated use. If decreased usage time
between charges becomes significant, it is
probably time to replace it with a new one.
• Each battery's life is governed by storage,
operating and environmental conditions.
About charging the battery pack
• Use the AC Adaptor (supplied) to charge the
designated batteries only. If you charge other
types of batteries, those batteries may leak, heat
up, burst, or give an electric shock, resulting in
burns or injury.
• Remove the charged battery from the AC
Adaptor.
• The CHG lamp of the supplied AC Adaptor
flashes in 2 patterns as follows:
Fast-flashing...Turns on and off rapidly at about
0.15-second intervals.
Slow-flashing...Turns on and off alternately for
about 1.5 seconds, and turns off completely for
about 1.5 seconds. The lamp repeats this
sequence.
• If the CHG lamp is fast-flashing, remove the
battery that is being charged, and then re-attach
the same battery again firmly. If the CHG lamp
continues fast-flashing, the cause could be that
the battery is damaged, or the battery is not a
designated type. Check the battery to confirm
whether it is a designated type or not. If it is a
designated type, remove the battery first, and
then attach a brand-new battery or another
known-to-be-good battery to see if the AC
Adaptor is working correctly. If the AC Adaptor
is working correctly, the cause could be that the
battery is damaged.
• If the CHG lamp is slow-flashing, the AC
Adaptor is in standby mode and charging is
suspended. When the ambient temperature is out
of the appropriate temperature range for
charging, the AC Adaptor suspends charging
automatically and enters standby mode. When
the ambient temperature returns to an
appropriate temperature, the AC Adaptor
restarts charging and the CHG lamp lights up.
We recommend charging the battery pack in an
ambient temperature of from 10 °C to 30 °C
(50 °F to 86 °F).
