Additional Information
About the “InfoLITHIUM” battery pack
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 your camcorder
and the 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.
Charging the battery pack
•Be sure to charge the battery pack before you start using your camcorder.
•We recommend charging the battery pack in an ambient temperature of between 10°C
to 30°C (50°F to 86°F) until FULL appears indicating that the battery pack is fully
charged, in the display window. 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 performance decreases in low-temperature surroundings. So, the time that the
battery pack can be used is shorter in cold places. We recommend the following to use
the battery pack longer:
– Put the battery pack in a pocket to warm it up, and insert it in your camcorder
immediately before you start taking shots.
– Use a large capacity battery pack (NP-FM50/FM70/QM71/FM90/FM91/QM91,
optional).
•Frequently using the LCD panel or frequently operating playback, fast forward or
rewind wears out the battery pack faster. We recommend using a large capacity
battery pack (NP-FM50/FM70/QM71/FM90/FM91/QM91, optional).
•Be certain to turn the POWER switch to OFF (CHG) when not taking shots or playing
back on your camcorder. Battery pack power 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 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 although 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 it is used in high
temperatures for a long time or left in a fully charged state, or the battery pack is
frequently used. Regard the remaining battery time indication as approximate.
•The E mark, indicating 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 5 to 10 minutes.
How to store the battery pack
•If the battery pack is not used for a long time, do the following once a year to maintain
proper function.
1. Fully charge the battery pack.
2. Discharge on your camcorder.
3. Remove the battery pack from your camcorder and store it in a dry, cool place.
•To discharge the battery pack on your camcorder, leave your camcorder in CAMERA
(standby) mode without a cassette inserted until the power goes off.
