About the “InfoLITHIUM” battery pack
This unit is compatible with the
“InfoLITHIUM” battery pack (M series). Your
camcorder operates only with the
“InfoLITHIUM” battery pack. “InfoLITHIUM”
M series battery packs have the
SERIES
TM
mark.
What is the “InfoLITHIUM”
battery pack?
The “InfoLITHIUM” battery pack is a lithium-
ion battery pack that has functions for
communicating information related to
operating conditions between the battery pack
and an AC adaptor/charger (optional).
The “InfoLITHIUM” battery pack calculates
the power consumption according to the
operating conditions of your camcorder, and
displays the remaining battery time in
minutes.
With an AC adaptor/charger (optional), the
remaining battery time and charging time are
displayed.
Charging the battery pack
•Be sure to charge the battery pack before you
start using your camcorder.
•It is recommended to charge the battery pack
in an ambient temperature of between
10°C to 30°C (50°F to 86°F) until POWER/
CHG (Charge) lamp turns off. If you charge
the battery pack outside of this temperature
range, you may not be able to efficiently
charge the battery pack.
•After charging is completed, either
disconnect the cable from the DC IN jack on
your camcorder or remove the battery pack.
Effective use of the battery pack
•Battery pack performance decreases in low-
temperature surroundings and recording
may not be possible even though the battery
time remaining may be as much as 20
minutes. We recommend the following to
ensure longer battery pack use:
– Put the battery pack in a pocket close to
your body to warm it up, and insert it in
your camcorder immediately before you
start taking shots.
– Use a large capacity battery pack (NP-
FM70/QM71/QM71D/FM91/QM91/
QM91D, optional).
•Frequently using the LCD screen or
frequently operating playback, fast forward
or backward wears out a battery pack faster.
It is recommended that you use the large
capacity battery pack (NP-FM70/QM71/
QM71D/FM91/QM91/QM91D, optional).
•Be sure to slide the POWER switch to OFF
(CHG) when not shooting or playing back on
your camcorder. The battery pack is also
consumed when your camcorder is in the
standby mode or playback is paused.
•Have spare battery packs handy for two or
three times the expected recording time, and
make a trial recording on DVD-RW before
the actual recording.
•Do not expose the battery pack to water. The
battery pack is not water-resistant.
Remaining battery time indicator
•If 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
so that the indication on the remaining
battery time indicator is correct. Note,
however, that the correct battery indication
sometimes will not be restored if the battery
is used in high temperatures for a long time
or left in a fully charged state, or the battery
pack is used frequently. Regard the
remaining battery time indication as the
approximate shooting time.
•The E mark indicating that there is little
remaining battery time sometimes flashes
depending on the operating conditions or
ambient temperature and environment even
if the remaining battery time is about 20
minutes.
How to store the battery pack
•If the battery pack is not used for a long time,
perform the following procedure once per
year to maintain proper battery function.
1. Fully charge the battery pack.
2. Discharge it using your camcorder.
3. Remove the battery from the camcorder
and store it in a dry, cool place.
•To use the battery pack up on your
camcorder, leave your camcorder in the
recording standby without a disc inserted
with the [A. SHUT OFF] to [NEVER] in the
(SETUP MENU) in the SETUP display
until the power goes off.
Battery life
•The battery life is limited. Battery capacity
drops little by little as you use it more and
more, and as time passes. When the available
battery time is shortened considerably, a
probable cause is that the battery pack has
reached the end of its life. Buy a new battery
pack.
•The battery life varies according to how it is
stored, the operating conditions, and the
environment in which each battery pack is
used.
