Getting Started: Charging the toothbrush Be sure to turn off the toothbrush before charging. Plug the power plug into the outlet. Place the handle in the charger. The charger indicator light will be lit, indicating the handle is charging. After the battery is fully charged, charge indicator light will turn off, indicating the toothbrush is fully charged. Notes: It takes at least 24 hours to charge the battery fully. When fully charged, the toothbrush can be used 20 pre-timed brush cycles, or approximately 10 days, if brushing twice daily. The toothbrush must be charged for 24 hours, if: this is the first time using the toothbrush; the toothbrush has not been used for more than three months; the charge is drained from use. To keep the battery fully charged, Aquasonic recommend that you keep the toothbrush in the charger when not in use. During charging, the toothbrush will get warm, but this is normal. The operating duration will become shorter as the battery gets older. If the toothbrush operates only for 1 short time after being fully charged, this means that the battery is nearing the end of its life cycle. Red indicator light is on during charging. Fill the green indicator light for 10 seconds, then turn off all lights.
