On the battery pack On charging the battery pack We recommend charging the battery pack in an ambient temperature of between 10°C to 30°C (50°F to 86°F). The battery pack may not be fully charged in temperatures outside this range. Effective use of the battery pack • Battery performance decreases in low temperature surroundings. So in cold places, the operational time of the battery pack is shorter. 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 the camera immediately before you start shooting. • The battery pack will run out quickly if you use the flash or zoom frequently. • We recommend having spare battery packs handy for two or three times the expected shooting time, 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. How to store the battery pack • Fully discharge the battery pack before storing and store it in a cool, dry place. To maintain the battery pack's function, fully charge the battery pack and then fully discharge it on the camera at least once a year while storing. • To use the battery pack up, leave the camera in slide show (page 45) playback mode until the power goes off. • To keep clean battery pack terminal and prevent short-circuiting, place the battery pack in a plastic bag, etc. when carrying and storing to isolate it from other metal objects, etc. On battery life • The battery life is limited. Battery capacity decreases over time and through repeated use. If decreased usage time between charges becomes significant, it would be best to replace it with a new one. • The battery life varies according to how it is stored and the operating conditions and environment in which each battery pack is used. 98
