6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Battery is discharged. | Charge the device using the Type-C cable. |
| Inaccurate measurements. | Laser lenses are dirty; measurement surface is too reflective/transparent; device is unstable during measurement. | Clean the laser lenses. Measure against a solid, non-reflective surface. Ensure the device is held steady. |
| Difficulty changing units. | Incorrect button press or timing. | Ensure you are pressing the UNIT button. Press it briefly to cycle through units. |
| Display is hard to read. | Font size or screen orientation not optimized. | Utilize the font enlargement and screen rotation features of the color backlit LCD display. |
