Cautions concerning the battery:
Read the following instructions
carefully when you use the battery.
Discharging:
Rechargeable batteries self-discharge
while not in use. Charge it regularly
before use.
Battery life:
Over time, the rechargeable battery
may gradually wear down. When
the operating time becomes shorter
even if the rechargeable battery is
fully charged under the specified
condition, replace it with a new one.
Operating temperature:
Rechargeable batteries are chemical
products. Battery efficiency may vary
even when operating within the
recommended temperature range.
This is an inherent nature of these
products.
Recommended temperature range
of use:
During operation:
0°C - 42°C
Charging:
5°C - 35°C
Storage for a long period:
–20°C - 60°C
Using the battery outside the above
temperature range may result in
declining efficiency and shorter
battery life.
Notes:
• When disposing the batteries,
always observe the local laws and
regulations. Contact your local
recycling center for proper disposal
methods.
• If battery is not fully discharged,
protect it against short-circuiting
(e.g. by taping the contacts) before
disposal.
For customers in Germany:
Olympus has a contract with the GRS
(Joint Battery Disposal Association) in
Germany to ensure environmentally
friendly disposal.
