You can change the burst modes to have the desired amounts each time you press the activation button. To change the modes, press the power button continuously until you reach your desired mode. The LEDs show the selected mode:
- Single burst: 1 LED
- Double burst: 2 LEDs
- Triple burst: 3 LEDs
Note: For optimal results, use the triple burst mode (default setting) from both the outside and inside of your teeth.
