7. USING THE BATTERY
Types of power source: "23. POWER SUPPLY SYSTEM"
The battery was not charged at the factory. Charge the battery fully before using the OS.
• The charger will become rather hot during use. This is normal.
• Do not use to charge batteries other than those specified.
• The charger is for indoor use only. Do not use outdoors.
• Batteries cannot be charged, even when the charging lamp is flashing, when the temperature is
outside the charging temperature range.
• Do not charge the battery just after charging is completed. Battery performance may decline.
• Remove batteries from the charger before putting into storage.
• When not in use, disconnect the power cable plug from the wall outlet.
• Store the battery in a dry room where the temperature is within the following ranges.
For long-term storage, the battery should be charged at least once every six months.
• Batteries generate power using a chemical reaction and as a result have a limited lifetime. Even
when in storage and not used for long periods, battery capacity deteriorates with the passage of
time. This may result in the operating time of the battery shortening despite having been charged
correctly. In this event, a new battery is required.
PROCEDURE
1. Connect the power cable to the charger and
plug the charger into the wall outlet.
2. Mount the battery in the charger by matching
