For Your Safety
The Battery and Power Supply
Note: Check the type of battery used in your camera and read
the appropriate sections.
WARNING: Battery shall not be exposed to excessive heat
such as sunshine, fire or the like.
The following describes the proper use of batteries and how
to prolong their life. Incorrect use can shorten battery life or
cause leakage, overheating, fi re, or explosion.
Li-ion BatteriesLi-ion Batteries
Read this section if your camera uses a rechargeable Li-ion
battery.
The battery is not charged at shipment. Charge the battery
before use. Keep the battery in its case when not in use.
■■ Notes on the BatteryNotes on the Battery
The battery gradually loses its charge when not in use.
Charge the battery one or two days before use.
Battery life can be extended by turning the camera off when
not in use.
Battery capacity decreases at low temperatures; a depleted
battery may not function when cold. Keep a fully charged
spare battery in a warm place and exchange as necessary,
or keep the battery in your pocket or other warm place and
insert it in the camera only when shooting. Do not place the
battery in direct contact with hand warmers or other heating
devices.
■■ Charging the Battery Charging the Battery
The battery can be charged using the camera and supplied
AC adapter or an optional BC-W235 dual battery charger.
Charging times will increase at ambient temperatures below
+10 °C (+50 °F) or above +35 °C (+95 °F). Do not attempt to
charge the battery at temperatures above +40 °C (+104 °F); at
temperatures below +5 °C (+41 °F), the battery will not charge.
Do not attempt to recharge a fully charged battery. The battery
does not however need to be fully discharged before charging.
The battery may be warm to the touch immediately after
charging or use. This is normal.
■■ Battery LifeBattery Life
A noticeable decrease in the length of time the battery will
hold a charge indicates that it has reached the end of its ser-
vice life and should be replaced.
If the battery is left for long periods without charging, you
may fi nd that its quality degrades or that it no longer holds a
charge. Charge the battery regularly.
■■ StorageStorage
If the camera will not be used for an extended period, store
it at room temperature with the battery charged to approxi-
mately one half to ⁄ capacity.
If the camera will not be used for an extended period, re-
move the battery and store it in a dry place with an ambient
temperature of from +15 °C to +25 °C (+59 °F to +77 °F). Do
not store in locations exposed to extremes of temperature.
