If one switch is not successful, you can press and hold again until the Bluetooth indicator light turns red and is constantly on
② Connect to the computer via Bluetooth and draw a few strokes on the digital board with a pen. If the pen moves in the same direction as the cursor inside the computer, it indicates that the gear is correct
Please note that! If the direction of the drawing line is not consistent, it indicates that the current gear is incorrect. You need to press and hold 【 K3 】 and 【 K4 】 simultaneously for 5 seconds to switch. If one switch is not successful, you can press and hold again to switch until the direction of the drawing line is consistent
