(1) Charge (if batteries are used)
1) Insert the AC adapter plug into a power supply.
2) Confirm the AC IN lamp light is green.
3) The internal microcomputer checks the voltage of the batteries and starts charging, if necessary. If it starts
charging, the CHARGE lamp lights, and the mark of the remaining amount of the batteries on the LCD panel will
be animated.
* There is no need to turn on the power.
4) When the CHARGE lamp turns off, charging has been completed.
CAUTION
• Do not connect other than AC120V or AC 230V. If it connects to others, it may cause a malfunction.
• Since the AC IN lamp lights up 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 charging normally takes approx. 5 hours, but it depends on battery use conditions. Older batteries are
especially prone to significantly shorter charging and operating times.
• The temperature of the batteries is measured during charging. Proper charging cannot be preformed if the
charger is placed in an environment which is subject to sharp temperature change (next to window, subject
to direct sunlight, near air outlet or fan heater). Place it in a place where temperature change is minimal.
• Charging may not be started in the following case:
• 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 temperature of the batteries is executively high or low. (Lower than apporox. 0 degree or higher than
approx. 40 degree)
• A battery is not connected.
• The voltage of a battery is abnormal. (See P.16 10. "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.
