Battery pack/ Battery charger • The charging time differs depending on the remaining capacity of the battery pack or charging conditions. • 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. • Connect the battery charger to the nearest wall outlet (wall socket). • Do not try to charge the battery pack again right after it has been charged, or when it has not been used after being charged. Doing so will affect the performance of the battery pack. • Do not charge any battery pack other than the "InfoLITHIUM" W series battery pack in the battery charger (supplied) with your camera. Batteries other than the specified kind may leak, overheat, or explode if you attempt to charge them, posing a risk of injury from electrocution and burns. • When the CHARGE lamp flashes, this may indicate a battery error or that a battery pack other than the specified type has been installed. Check that the battery pack is the specified type. If the battery pack is the specified type, remove the battery pack, replace it with a new one or another one and check if the battery charger operates correctly. If the battery charger operates correctly, a battery error may have occurred. • If the battery charger is dirty, charging may not be performed successfully. Clean the battery charger with dry cloth, etc. Notes on using the battery pack • Use only an NP-FW50 battery pack. • The displayed level may not be correct under certain circumstances. • 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. 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 and the speed of continuous shooting slows down. We recommend that you 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, use continuous shooting often, turn the camera on and off 203 Trouble shooting/Others (Advanced operations)
