|---|---|---|
| Device does not power on. | Battery is dead or incorrectly installed. | Replace battery with a new CR2 3-volt Lithium battery, ensuring correct polarity. |
| Inaccurate or inconsistent readings. | Target is too small, too far, or non-reflective. Environmental conditions (fog, heavy rain). | Aim at a larger, more reflective target. Ensure clear line of sight. Ranging performance may be reduced in adverse weather. |
| Display is dim or flickering. | Low battery. | Replace the battery. |
| "E" or "Error" displayed. | Measurement out of range or laser blocked. | Ensure target is within 10-600 yards. Check for obstructions in the laser path. |
