To charge the DOMO DO9233TB Electric Toothbrush, follow these steps:
1. Insert the plug of the charging cradle into a power socket with an output voltage of 100 to 240 Volts.
2. Place the rechargeable hand unit facing forwards in the charging cradle.
3. The red indicator lamp on the charging cradle will light up, indicating that the device is charging.
4. The lamps above the different programs on the hand unit will start to light up incrementally.
5. The red lamp will turn green when the battery is fully charged.
It is recommended to fully charge the battery for 24 hours before first use and then let it fully discharge during use. Repeat the charging/discharging process every six months to maximize the capacity and service life of the rechargeable batteries. The hand unit should always be placed in the charging cradle after use to maintain optimal capacity.
