When your interactive whiteboard has problems using it, please check the following:
1. Is your computer activated? Is it working properly? If it is not normal, please try another computer.
2. Is your projector turned on? Can I display the screen of my computer normally? If it is not normal, check if the connection between the projector and the projector and the computer is normal, and the projector is powered normally. Try connecting the projector's VGA cable directly to the computer's display card? Ask a professional to check if the relevant cable is faulty. Are you sure that the central controller's VGA splitter has a problem? If yes, please contact us.
3. Is your central controller power indicator on? Is the switch open?
4. Is the USB cable connection between the computer and the interactive whiteboard central controller reliable?
5. Is the network cable connection between the central controller and the interactive whiteboard reliable?
6. When the pen does not touch the whiteboard, is the indicator light near the network cable connection interface of the interactive whiteboard red? If it is green, please re-plug the network cable interface. Are you sure step 3? If it still does not light, please contact us.
7. Is there a "whiteboard" icon in the lower right corner of your computer screen? Have you run the "Whiteboard Scanning" program? Is the driver for the interactive whiteboard installed on your computer? Are you sure the USB cable is ok? Ask a professional to confirm if there is a problem with the USB interface of the central controller. If yes, please contact us.
8. If you can answer the above questions affirmatively, please restart your computer and try again, and confirm step 7 again.
9. Please pick up the electronic pen, click on the "red marker" button on the side of the whiteboard, and then draw a few strokes on the interactive whiteboard? Is there a reaction to changing to another pen? Try replacing the battery of the electronic pen with a 7-cell alkaline battery.
10. If you still cannot solve your problem after performing the above checks, please contact a professional.
