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
If unit does not turn on – LCD does not illuminate:
• Depress POWER button.
• Check and if necessary, replace battery.
If unit powers down (display goes blank when attempting to power the laser):
• The battery is either weak or low quality. Replace the battery with a good quality
3 -volt lithium battery.
If target range cannot be obtained:
• Make sure LCD is illuminated.
• Make sure that the power button is being depressed.
• Make sure that nothing, such as your hand or finger, is blocking the objective lenses (lenses closest
to the target) that emit and receive the laser pulses.
• Make sure unit is held steady while depressing power button.
NOTE: 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.
