Technical Notes and Index
The Battery
• Be sure to read and follow the warnings in “For Your Safety” (A viii-xi) before use.
• Check the battery level before using the camera and replace or charge the battery if
necessary. Do not continue charging once the battery is fully charged as this will result in
reduced battery performance. Whenever possible, carry a fully charged spare battery when
taking pictures on important occasions.
• Do not use the battery at ambient temperatures below 0°C (32°F) or above 40°C (104°F).
• Charge the battery indoors with an ambient temperature of 5°C to 35°C (41°F to 95°F)
before use.
• When the battery temperature is between 45°C–55°C (113°F–131°F), the chargeable
capacity may decrease.
• When charging the battery inserted into this camera using the Charging AC Adapter or a
computer, the battery is not charged at ambient temperatures below 5°C (41°F) or above
55°C (131°F).
• Note that the battery may become hot during use; wait for the battery to cool before
charging. Failure to observe these precautions could damage the battery, impair its
performance, or prevent it from charging normally.
• On cold days, the capacity of batteries tends to decrease. If an exhausted battery is used at
a low temperature, the camera will not turn on. Be sure that the battery is fully charged
before heading outside to take pictures in cold weather. Keep spare batteries in a warm
place and exchange as necessary. Once warmed, a cold battery may recover some of its
charge.
• Dirt on the battery terminals can prevent the camera from functioning. Should the battery
terminals become dirty, wipe them off with a clean, dry cloth before use.
• If the battery will not be used for some time, insert it in the camera and completely exhaust
it before removing it for storage. The battery should be stored in a cool location with an
ambient temperature of 15°C–25°C (59°F–77°F). Do not store the battery in hot or
extremely cold locations.
• Always remove the battery from the camera or battery charger when it is not being used.
When inserted, minute amounts of current are drawn from the battery even when not in
use. This may result in excessive draining of the battery and complete loss of function.
Turning the camera on or off while the battery is exhausted can result in reduced battery
life.
• Recharge the battery at least once every six months and completely exhaust it before
returning it to storage.
