Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Battery is dead or incorrectly installed. | Check battery polarity. Replace with a new CR2 battery. |
| Display is blurry. | Diopter not adjusted correctly. | Rotate the eyepiece knob to adjust the diopter until the image is clear. |
| Inaccurate distance readings. | Target is too close/far, or environmental interference. | Ensure target is within 6-656 yards. Avoid measuring through fog or heavy rain. Ensure a steady hand or use a tripod. |
| Flag-Lock not working. | Flagpole is beyond 300 yards or not clearly isolated. | Ensure the flag is within 300 yards. Try to isolate the flag from background objects by slowly scanning. |
