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 an optional AC adaptor/charger. 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 the CHARGE lamp goes off, indicating that the battery pack is fully charged. If you charge the battery 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. So, the time that the battery pack can be used is shorter in cold place. 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 the large capacity battery pack (NP-FM70/FM90/FM91, optional). •Frequently using the LCD panel or frequently operating playback, fast forward or rewind wears out the battery pack faster. We recommend using the large capacity battery pack (NP-FM70/FM90/FM91, optional). •Be certain to turn the POWER switch to OFF (CHARGE) when not taking shots 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 recordings before taking the actual recording. • Do not expose the battery pack to water. The battery pack is not water resistant. Additional Information Remaining battery time indicator •If the power may go 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 the approximate shooting time. •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 about five to ten minutes. How to store the battery pack •Even if the battery pack is not used for a long time, store it in a dry, cool place after fully charging it once per year and then using the battery pack up on your camcorder. This is to maintain the battery pack's functions. •To use the battery pack up on your camcorder, leave your camcorder in the shooting mode until the power goes off without a cassette inserted. 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. Please buy a new battery pack. •The battery life varies according to how it is stored and operating conditions and environment for each battery pack. 171
