  1. How do I know wether the battery of Knorvay N99C Powerpoint Presenter has enough power?
    You can directly press the laser key to check the power. If there's no laser beam released when you pressing it, please charge it immediately. And If the indicator flashes slowly, it also means the power is not enough.
  2. What should I do when the mouse cursor does not move smoothly and accurately?
    In this case, you'd better calibrate the product. Place the Powerpoint Presenter on a horizontal and stable plane, then simultaneously press the left mouse button and air mouse button for 2 secs. Blue indicator flashes mean the product has been in the calibration mode, then unclench your hands and try to keep the product still. If the blue indicator flashes 3 secs and goes out after 5 secs lighting, it shows that your calibration has been completed.
