CAUTION:

●When the battery charger has been continuosly used, the battery charger will 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 flickers 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.

●Since the built-in micro computer takes about 3 seconds to confirm that the battery being charged with UC 24YF is taken out, wait for a minimum of 3 seconds before reinserting it to continue charging. If the battery is reinserted within 3 seconds, the battery may not be properly charged.

Regarding electric discharge in case of new batteries, etc.

As the internal chemical substance of new batteries and batteries that have not been used for an extended period is not activated, the electric discharge might be low when using them the first and second time. This is a temporary phenomenon, and normal time required for recharging will be restored by recharging the batteries 2 – 3 times.
