Charger Unit Precautions
• The charger unit becomes slightly warm during
charging. This is normal and does not indicate
malfunction.
• Unplug the charger unit from the power outlet
whenever you are not using it.

Battery Precautions
Precautions During Use
• Use only the charger unit that comes with the camera
to charge the batteries. Never use any other type of
charger unit for charging.
• New batteries are not charged. Be sure to charge the
batteries before using them for the first time.
• Cold tends to shorten battery life, so the amount of
power provided by fully charged batteries may be
shorter in cold areas.
• Charge the batteries in a location where the
temperature is in the range of 10 ° C to 35 ° C (50 ° F to
95
°
F). Charging outside this temperature range can
cause charging to take longer than normal or even
cause charging to fail.
• Very limited operation following a full charge indicates
that the batteries have reached the end of their service
life. Replace the batteries with new ones.
Storage Precautions
• Though rechargeable nickel-metal hydride batteries
provide high power in a compact configuration, storing
them for long periods while they are charged can cause
batteries to deteriorate.
— Always remove the batteries from the camera when
you are not using it. Leaving batteries in the camera
can cause them to discharge and go dead or even
leak.
— Store batteries in a dry place where the temperature
is 20 ° C (68 ° F) or lower.
— If you store batteries for a long time, charge them
two or three times before using them again.

Optional Batteries
Use of SANYO Electric Co., Ltd. Rechargeable nickel-
metal hydride batteries (HR-3U) is recommended for this
camera. Proper operation cannot be guaranteed when
other brands of rechargeable batteries are used.
IMPORTANT!
• Never mix two batteries of different brands, ages, or
charge levels. Doing so creates the risk of shortened
battery life and can even damage the camera.
