Troubleshooting

1. Open the program and an error is shown as “No valid USB Key for hand touch whiteboard found”.
2. First check if the connection of USB cable is correct.
3. Please confirm if the USB cable has not been cut or spliced.
4. Please confirm if the system is equipped with a recovery card. Please add the calibration program to the recovery card.
5. See if the system uses a solid state disk. If so please contact technical support.
6. Change to another one USB port or another computer and test again.
7. After the auto-calibration, the cursor does not synchronize with the finger.
8. Open “tuning webcam image mode”, confirm whether the proportion of projection screen (photoed by camera) meets the requirement.
9. Open “tuning laser transmitter image mode”, confirm whether the laser film is within 5mm above whiteboard surface, and the image appears to touch the board lightly.
10. If the two steps above meet the requirements and the problem persists, contact technical support.
11. When doing auto-calibration, it prompts failure?
12. Open “tuning webcam image mode”, observe whether the projection screen (photoed by camera) is within the calibration interface or not, and if the proportion of the image meets the requirements, and whether the image is clear or not.
13. Toggle “tuning webcam image mode” and “tuning laser transmitter image mode” repeatedly to observe if the brightness of the image changes. If the image is always black, please change the sensor.
14. Observe the picture after the calibration failure and analyze the overall brightness of the “black and white checkerboard”. If it is too bright, please adjust the value of the average brightness down to 40, and adjust the value of gray down to 250; if it is totally black, please adjust the value of the average brightness up to 140, and adjust the value of gray down to 250.
15. If auto-calibration still cannot be performed after adjusting the parameters, please perform manual calibration or contact technical support.
16. Device is installed according to the requirements, and auto-calibration is successful. Yet the operation is not sensed well in top right corner, and the writing is non-continuous.
17. Open the calibration program, write in the non-continuous area, and observe whether there is a lightspot in the non-continuous area. If not, please change the emitter.
18. If there is a spot, and the spot is small. Firstly adjust the bright coefficient, adjust the value up to around 170.
19. Do lightspot sampling
