CAUTION
• Connect to AC120 V or AC230 V power supply only. Otherwise,
malfunction will occur.
• Since the AC IN lamp lights to indicate that the supply power is on,
it does not go out even after a charge is completed. See the
CHARGE lamp to check the charging conditions.
• The standard charging time is about 5 hours, but it varies
depending on use, condition of batteries, temperature and
whether the batteries are new or old. Please note, older batteries
may remarkably shorten both the charging and operating time.
• When charging a battery, the temperature of the battery is
measured. Therefore, if this product is placed in an environment
where the temperature changes rapidly (for example, near to a
window exposed to sunlight, near the outlet of a air conditioner, or
heater), the battery cannot be properly charged. Put this product
in a place where the temperature varies little.
• In the following cases, it may not start charging:
- The temperature of a battery is too low or too high (less than 0°C
(32°F) or more than 40°C (104°F)).
- The voltage of a battery is sufficient (this does not necessarily
mean fully charged).
- A battery is not connected.
- The voltage of a battery is abnormal (see
11 Error Code
).
• Batteries are automatically charged depending on conditions,
even when the power is on. But when the motor handpiece is
used, charging is suspended to protect the battery.
