Battery
The battery is a rechargeable lithium ion battery. Its ability to generate power comes
from the chemical reaction that takes place inside it. This reaction is susceptible to
the surrounding temperature and humidity. If the temperature is too high or too low,
the operating time of the battery will become shorter.
Always remove the battery after use.
• Store the removed battery in the battery case (supplied).
If you drop the battery accidentally, check to see if the body
of the battery and the terminals are damaged.
• Inserting a damaged battery in the camera will damage the
camera.
Bring charged spare batteries when going out.
• Be aware that the operating time of the battery becomes shorter in low temperature
conditions such as at a ski resort.
• When you travel, do not forget to bring the battery charger (supplied) so that you can
charge the battery in the country that you are traveling in.
Dispose of unusable battery.
• The battery has a limited life.
• Do not throw battery into fire because it may cause an explosion.
• An unusable battery should be discarded in accordance with battery recycling laws.
Call the RBRC hotline on 1-800-822-8837 for information.
Do not allow battery terminals to come into contact with metal objects (such as
necklaces, hairpins, etc.).
• This can cause short circuiting or heat generation and you may be badly burned if you
touch the battery.
Charger
• If you use the battery charger near a radio, the radio reception may be disturbed.
• Keep the charger 1 m (3.28 feet) or more away from radios.
• The charger may generate whirring sounds when it is being used. This is not a
malfunction.
• After use, be sure to disconnect the power supply device from the electrical outlet. (A
very small amount of current is consumed if it is left connected.)
• Keep the terminals of the charger and battery clean.
