- Power On: Press the Power Button once to turn on the toothbrush. It will start in the last used mode or a default mode.

7.2 Brushing Technique
For optimal cleaning, follow these steps:
- Place the brush head against your teeth at a slight angle towards the gumline.
- Gently move the brush head slowly from tooth to tooth, allowing the sonic vibrations to do the work. Do not scrub vigorously.
- Brush each quadrant of your mouth (upper right, upper left, lower right, lower left) for 30 seconds. The toothbrush may have a built-in timer that pauses briefly every 30 seconds to signal you to move to the next quadrant, and automatically shuts off after 2 minutes.
- Brush all surfaces of your teeth: outer, inner, and chewing surfaces.
- After brushing, rinse your mouth and the brush head thoroughly.
