8. Troubleshooting
If you encounter issues with your device, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Depleted or incorrectly inserted batteries. | Check battery polarity and replace with fresh AAA batteries. |
| Inaccurate measurements. | Dirty laser lens, unsuitable target surface, or strong light interference. | Clean the laser lens. Ensure the target surface is solid and reflective. Avoid measuring in direct sunlight or very bright conditions. |
| Laser beam not visible. | Device not powered on, or operating in very bright conditions. | Ensure the device is powered on. The laser beam may be less visible in bright environments; try shading the target area. |
