Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not turn on. | Battery is depleted or inserted incorrectly. | Replace the battery with a new CR2 lithium battery, ensuring correct polarity. |
| No distance displayed after measurement. | Target is out of range, laser beam is blocked, or device is not aimed correctly. | Ensure the target is within the specified range. Aim directly at the target. Check for obstructions. |
| Inaccurate distance readings. | Environmental conditions (fog, rain), target surface reflectivity, or incorrect mode selection. | Wait for clearer conditions. Ensure the correct mode is selected for your application. Try measuring a different part of the target. |
