Using the Battery When Cold
On cold days, the capacity of batteries tends to decrease. If an exhausted battery is
used at a low temperature, the camera may not turn on. Keep spare batteries in a
warm place and exchange as necessary. Once warmed, a cold battery may recover
some of its charge.
Battery Terminals
Dirt on the battery terminals may prevent the camera from functioning. Should the
battery terminals become dirty, wipe them off with a clean, dry cloth before use.
Charging an Exhausted Battery
Turning the camera on or off while an exhausted battery is inserted in the camera
may result in reduced battery life. Charge the exhausted battery before use.
Storing the Battery
• Always remove the battery from the camera or optional battery charger when it is
not being used. Minute amounts of current are drawn from the battery while it is in
the camera, even when not in use. This may result in excessive battery drain and
complete loss of function.
• Recharge the battery at least once every six months and completely exhaust it
before returning it to storage.
• Put the battery in a plastic bag, etc. in order to insulate it and store it in a cool place.
The battery should be stored in a dry location with an ambient temperature of 15°C
to 25°C (59°F to 77°F). Do not store the battery in hot or extremely cold locations.
Battery Life
A marked drop in the time a fully charged battery retains its charge, when used at
room temperature, indicates that the battery needs to be replaced. Purchase a new
battery.
Recycling Used Batteries
Replace the battery when it no longer holds a charge. Used batteries are a valuable
resource. Please recycle used batteries in accordance with local regulations.
The Charging AC Adapter
• The Charging AC Adapter EH-71P/EH-71PCH is for use only with compatible
devices. Do not use with another make or model of device.
• Do not use any USB cable other than the UC-E21. Using a USB cable other than the
UC-E21 could result in overheating, fire or electric shock.
• Do not, under any circumstances, use another make or model of AC adapter other
than Charging AC Adapter EH-71P/EH-71PCH, and do not use a commercially
available USB-AC adapter or a battery charger for a mobile phone. Failure to
observe this precaution could result in overheating or in damage to the camera.
• The EH-71P/EH-71PCH is compatible with AC 100–240 V, 50/60 Hz electrical
outlets. When using in other countries, use a plug adapter (commercially available)
as necessary. For more information about plug adapters, consult your travel
agency.
