Determining the full charge of your Medisana HM 645 Hand Massager is straightforward. Here's how: First, plug the provided 9V/1A charging adapter into both the massager's charging socket and a power outlet. The indicators on the unit will then show the battery's charge status. During charging, the LEDs will light up or blink. Once the battery is fully charged (typically after 2 to 3 hours), all four charging LEDs will illuminate continuously in blue. Please note that the massager cannot be used while it is charging. By watching these LED indicators, you'll easily know when your Medisana HM 645 Hand Massager is ready to provide a relaxing massage.
