NOTICE
●
This function is not activated unless this product is powered by the AC adaptor�

It takes about maximum of 5 hours to discharge the battery�
●
It takes 5 hours to discharge and 5 hours to recharge� Therefore, total of about 10 hours are
required�
●
This function is not required for each charging� Try this function, if the operating time is shortened
even if the battery is relatively new�

Do not repeat activation and deactivation of the refresh mode in a short time� It may result in
enhancement of the memory effect�
