* Use a 100 to 240 V AC single-phase power supply. However, if the power
supply voltage exceeds 100 V, provide a power supply cable that complies
with the laws, regulations, and safety standards of the country or region
where it is being used.
* If the [CHARGE] lamp does not change color to green even considerably after
15 hours of charging, a probable cause is a malfunctioning battery.
Immediately disconnect the power cable, and contact your Sibata distributor.
* Be sure to ground this product. Before inserting the power cable into the
power outlet, be sure to ground this product beforehand.
* When inserting the ground lead into the ground terminal, disconnect the
power plug from the main unit power outlet. Failure to do so might cause
electric shock.
* Immediately after the battery unit is purchased or when the battery unit has
not been used for several months, the lamp might change color to green
several minutes after charging is started and charging might not be possible.
This is due to temporary overdischarge. If this happens, re-attach the battery
unit to the charger and re-charge the battery unit. If the problem is not
remedied by repeating this procedure several times, a probable cause is a
deteriorated rechargeable battery. Ask for repair.
