If the board has a problem with maintaining the balance or one side works differently than the other (faster or slower), you need to calibrate the sensors in the board. There are two sensors in the boards – independent for each side, so it is important that both parts of the board are aligned with each other during calibration. The board should be set, for example, next to the wall, and then two small levels should be placed on both sides of the board. Thanks to this, the level will be set. Then press the on button for 3 seconds – the front lights of the board will start to flash faster and the calibration process will start. During this time, you can not move the board. When the lights stop blinking the calibration has been completed.
