To charge the battery pack
Be sure to charge the battery pack before you start using this product.
We recommend that you charge the battery pack in an ambient temperature range of 10
˚C to 30 ˚C (50 °F to 86 °F) until the POWER/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.
The POWER/CHG (charge) lamp flashes during charging under the following conditions.
The battery pack is not inserted correctly.
The battery pack is damaged.
The temperature of the battery pack is low.
Remove the battery pack from this product and put it in a warm place.
The temperature of the battery pack is high.
Remove the battery pack from this product and put it in a cool place.
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. If that
happens, one of the following is recommended to enable longer use of the battery pack:
Put the battery pack in a pocket to warm it up, and install it on this product immediately before you
start shooting.
Use a large capacity battery pack: NP-FV70/NP-FV100A (sold separately).
Frequent use of the LCD monitor or a frequent playback, fast forward or reverse operation
wears out the battery pack faster.
Be sure to close the LCD monitor when not recording or playing back on this product. The
battery pack is also consumed when this product 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 power indicator
When the power goes off even though the remaining battery power indicator indicates that
the battery pack has enough power to operate, charge the battery pack fully again.
Remaining battery power 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.
Depending on the operating conditions or ambient temperature, the
indicates a low battery may flash even if there are still 20 minutes of power remaining.
