Rangefinder Tips:
1, It is normal to see a small bright line flashing on the display when using the rangefinder at night. This small
line is the laser signal beam from the rangefinder, and the place where this small line reaches is the actual
measurement point.
2, Because the laser rangefinder and objective lens are at different places, when users observe the near
targets and distant targets, the small LRF line will appear at different positions on the display. This is normal.
3, The factory has calibrated the small LRF line and reticle before product delivery. But transportation
vibrations may cause the small line and reticle to separate a little. This is also normal.
4, In poor atmospheric conditions, the device may fail to measure the distance, such as during rain or snow,
fog, high humidity, smog, dusty environment, etc. During such conditions, you might only be able to
measure distance of the near targets or targets with high reflection rate.
