●
When the battery charger has been continuosly
used, the battery charger will be heated, thus
constituting the cause of the failures. Once the
charging has been completed, give 15 minutes rest
until the next charging.
●
If the battery is rechraged when it is warm due to
battery use or exposure to sunlight, the pilot lamp
may light in green.
The battery will not be recharged. In such a case,
let the battery cool before charging.
●
When the pilot lamp flikers rapidly in red (at 0.2–
second intervals), check for and take out any
foreign objects in the charger's battery installation
hole. If there are no foreign objects, it is probable
that the battery or charger is malfunctioning. Take
it to your authorized Service Center.
