CLEANING

Gently blow away any dust or debris on the lenses (or use a soft lens brush). To remove dirt or fingerprints, clean with a soft cotton cloth, rubbing in a circular motion. Use of a coarse cloth or unnecessary rubbing may scratch the lens surface and eventually cause permanent damage. For a more thorough cleaning, photographic lens tissue and photographic-type lens cleaning fluid or isopropyl alcohol may be used. Always apply the fluid to the cleaning cloth - never directly on the lens.

Trouble Shooting Table

• The battery is either weak or low quality. Replace the battery with a good quality lithium battery.

There is no reset button to clear last range reading before ranging another target.

The last range reading does not need to be cleared before ranging another target. Simply aim at the new target using the LCD’s reticle, depress the power button and hold until new range reading is displayed.
