On the "InfoLITHIUM" battery pack Use only an NP-FM500H battery pack. What is an "InfoLITHIUM" battery pack? An "InfoLITHIUM" battery pack is a lithium-ion battery pack that has functions for exchanging information related to operating conditions with your camera. Using the "InfoLITHIUM" battery pack, the remaining battery time in percent figures is displayed according to the operating conditions of your camera. On charging the battery pack We recommend charging the battery pack in an ambient temperature of between 10 to 30°C (50 to 86°F). You may not be able to efficiently charge the battery pack outside of this temperature range. 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 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 camera immediately before you start shooting. • The battery pack will run out quickly if you use the flash frequently. • We recommend having spare battery packs handy, and making trial shots before taking the actual shots. • Do not expose the battery pack to water. The battery pack is not water-resistant. • Do not leave the battery pack in extremely hot places, such as in a car or under direct sunlight. On the remaining battery indicator The power may go off although the battery remaining indicator shows there is enough power to operate. Use the battery pack up and charge the battery pack fully again so that the indication on the battery remaining indicator is correct. Note, however, that the correct battery indication sometimes will not be restored if the battery pack is used in high temperatures for a long time, left in a fully charged state or used frequently. How to store the battery pack If the battery pack is not to be used for a long time, fully charge it and then fully use it up once a year on your camera before storing the battery pack in a dry, cool place. Repeat this charging and using up once a year to maintain the battery pack's function. On battery life • The battery life is limited. Battery capacity decreases little by little as you use it more and more, and as time passes. If the battery operating time seems 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 and the operating conditions and environment in which each battery pack is used. Others 163
