CAUTION:
Repair is required if the receptacle is not secured
properly or the power cord does not stay in the
receptacle. Consult your electrician. Using the
charger in this condition may lead to fire.
If the charge status lamp is blinking red rapidly
(in 0.2 second intervals), check that the hole for
connecting the battery is not obstructed. Remove
any obstructions. If no obstructions are found, the
battery or charger may be malfunctioned. Return
both to your place of purchase.
If the charge time lamp does not light when the
power cord is connected to the receptacle,
disconnect the power cord, and check that the
battery is attached correctly.
The battery retains heat when used or left for
prolonged periods in direct sunlight. In this state,
the overheat lamp lights green, and the battery
cannot be charged immediately. Leave the battery
inserted in the charger, and charging will
commence when the battery cools down.
If the lamp goes out while charging, disconnect
the power cord, and leave for 3 to 5 minutes before
reconnecting. If the problem persists, call for
repairs.
Leave 5 minutes between charging batteries as
the charger may overheat leading to malfunction.
