operating conditions between this product and
an AC Adaptor/charger (sold separately).
The “InfoLITHIUM” battery pack calculates the
power consumption according to the operating
conditions of this product, and displays the
remaining battery time in minutes.
To charge the battery pack
Be sure to charge the battery pack before you
start using this product.
We recommend charging the battery pack in
an ambient temperature of from 10  C to 30  C
(50 °F to 86 °F) until the CHG (charge) lamp
turns off. If you charge the battery pack outside
of this temperature range, you may not be able
to charge it efficiently.
To use the battery pack effectively
Battery pack performance decreases when the
ambient temperature is 10  C (50 °F) or below,
and the length of time you can use the battery
pack becomes shorter. In that case, do one
of the following to use the battery pack for a
longer time.
Put the battery pack in a pocket to warm it
up, and install it on this product right before
you start taking shots.
Use a large capacity battery pack (NP-FV100).
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 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.
