Effective use of the battery
• We recommend that you use batteries until they are
completely drained before charging them.
• Battery performance decreases in low-temperature
surroundings, and the battery life is shortened under
such circumstances. To use the battery longer, we
recommend you keep the battery in its case in a
pocket close to your body to warm it, and insert it in
your camera just before you start shooting.

• If you use the LCD screen with [LCD LIGHT] to
[ON], the battery power will be used up faster.
• We recommend having spare batteries handy for two
or three times the expected shooting time, and try test
