CLEANING AND GENERAL CARE
The lenses of your Bushnell Nitro laser rangefinder are fully multi-coated for highest light transmission. As with any multi-
coated optics, special care must be taken in cleaning the lenses. Follow these tips for proper lens cleaning:
• Blow away any dust or debris on the lens (or use a soft lens brush).
• To remove dirt or finger prints, clean with the supplied micro-fiber cloth rubbing in a circular motion. Use of a coarse
cloth or unnecessary rubbing may scratch the lens surface and eventually cause permanent damage. The included
washable microfiber cleaning cloth is ideal for the routine cleaning of your optics. Simply breathe lightly on the lens to
provide a slight amount of moisture, then gently rub the lens with the microfiber cloth.
• 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.
All exterior lens surfaces have our new EXO Barrier™ coating (in addition to full multi-coating). EXO Barrier, quite simply,
is the best protective lens coating technology Bushnell has ever developed. Added at the end of the coating process, EXO
Barrier molecularly bonds to the lens and fills the microscopic pores in the glass. The result is an ultra-slick coating that repels
water, oil, fog, dust and debris - rain, snow, fingerprints and dirt will not stick. EXO Barrier is built to last: the bonded coating
will not fade with the passage of time or normal wear and tear.
The rangefinder is manufactured and tested to withstand water exposure up to IPX4 standards. It is water resistant, but
should not be submerged.
TROUBLESHOOTING
Never disassemble your laser rangefinder. Irreparable damage can result from unauthorized service attempts,
which also void the warranty.
If unit does not turn on, display does not illuminate:
• Depress Power/Fire button.
• Check and if necessary, replace battery. If unit does not respond to button presses, replace the battery with a good
quality CR2 3-volt Lithium 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 new 3 -volt lithium battery (CR2).
If target range cannot be obtained:
• Make sure the display is illuminated.
• Make sure that the Power/Fire button is being depressed.
• Make sure that nothing, such as your hand or finger, is blocking the lenses at the front of the rangefinder that emit and
receive the laser pulses.
• Make sure unit is held steady while depressing Power/Fire button.
NOTE: The last range reading does not need to be cleared before ranging another target. Simply aim at the new target
using the display reticle, depress the power button and hold until new range reading is displayed.
UPGRADE OPTIONS
The Nitro is ready to use out of the box with Applied Ballistics engine at the Ultralite level, but is upgradeable
if you ever need more distance and advanced data (spin drift and coriolis correction, sight height, etc) in your
ballistic solutions. Through the Bushnell Ballistics app (available for iOS and Android), the ballistics engine can
be upgraded from Ultralite to Sportsman or Elite. The standard, Ultralite version may be upgraded to either level,
and the Sportsman version may be upgraded to Elite. More information about the available upgrades, including
specific features and ranging capability, is available at www.bushnell.com and through the Ballistics app.
