• Frequent use of the LCD screen or a frequent
playback, fast forward or rewind operation
wears out the battery pack faster.
We recommend using a large capacity battery
pack: NP-F770/F970 (sold separately).
• Be sure to set the POWER switch to OFF when
not recording or playing back on your
camcorder. The battery pack is also consumed
when your camcorder is in recording standby or
playback pause.
• Have spare battery packs ready for two or three
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 time
indicator
• When the power goes off even though the
remaining battery time indicator indicates that
the battery pack has enough power to operate,
charge the battery pack fully again. Remaining
battery time 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 time indication as a rough
guide only.
• The E mark that indicates low battery flashes
even if there are still 5 to 10 minutes of battery
time remaining, depending on the operating
conditions or ambient temperature.
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
(p. 14).
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.
• Use the AC Adaptor/Charger (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/Charger.
• The CHARGE lamp of the supplied AC
Adaptor/Charger 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 CHARGE lamp is fast-flashing, remove
the battery that is being charged, and then re-
attach the same battery again firmly. If the
CHARGE 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/Charger is working correctly. If
the AC Adaptor/Charger is working correctly,
the cause could be that the battery is damaged.
• If the CHARGE lamp is slow-flashing, the AC
Adaptor/Charger is in standby mode and
charging is suspended. When the ambient
temperature is out of the appropriate
temperature range for charging, the AC
Adaptor/Charger suspends charging
automatically and enters standby mode. When
the ambient temperature returns to an
appropriate temperature, the AC Adaptor/
Charger restarts charging and the CHARGE
lamp lights up. We recommend charging the
battery pack in an ambient temperature of
between 10 °C to 30 °C (50 °F to 86 °F).
