NOTICE

● Do not use this charger if the power cord is wound around the unit.

Otherwise, the charger may overheat and be damaged.

● Make sure that the charging plug and the battery charging connector are free of dust, dirt,

oil, and moisture. Also, do not insert any metallic object or other foreign substance into the

plug or the connector, for this may cause the charger to malfunction or damage the battery.

● Do not place the charger in locations exposed to direct sunlight, near a heater or other heat

source, or where the temperature may drop below freezing.

If the charger or the battery becomes hot, the charger protection function may prevent the

unit from starting or turn it off while it is charging.

Also, the protection function activates if the charger is cold.

● Keep the area around the charger free of other objects and do not place a cover or similar

item over the unit.

The charger protection function may activate if the flow of air is blocked.

● Be sure to use the genuine power cord.
