IPD (INTERPUPILLARY DISTANCE) ADJUSTMENT
The spacing between the pupils of your eyes, called "interpupillary distance," varies from person to person. To match your ranging binoculars to your IPD or "eye to eye" width:
• Point them at a white wall or blank area of the sky. Hold the ranging binoculars and view through them as you usually would. Don't worry about focus yet.
• Grasp each side of the ranging binocular firmly. Move the left and right sides closer together or farther apart (Fig. 3) until you see a single image with no shaded areas.
NECKSTRAP ATTACHMENT
Attach the neck strap by threading the ends of the neck strap through the strap lug (Fig. 4) on each side of the ranging
binocular. Then back through the plastic buckle on the strap (Fig. 5). Adjust the position of the ranging binoculars on your
chest, as they hang around your neck, to your preference by changing the length of the strap section. Buckle by an equal
amount on each side. Tug on the ranging binocular to make sure it is securely fastened to the strap before letting go of it. If
you prefer to use an aftermarket strap with metal O-rings, use plastic zip ties to strap to the lugs rather than installing them
directly on the lug. Doing this avoids damage to the finish of the ranging binocular via contact with the rings.
BATTERY ACTIVATION / BATTERY LIFE INDICATOR
Before first use: Remove the battery compartment cover by using a coin to rotate the cover counterclockwise.
Remove and discard the red plastic disc covering the positive battery terminal, then replace the battery cover.
Note: It is recommended that the CR2 3-volt lithium battery be replaced at least once every 12 months. Please insert
the negative end into the compartment.

BASIC OPERATION
• While looking through the laser ranging binocular, press and release the Power/Fire button to activate the display.
• If the display appears blurry, rotate the rubber eyecup/diopter adjustment in either direction until the display is sharp for your vision.
• Placing the aiming circle (located in the center of the display) on a target at least 10 yards away, depress and hold the Fire button down until the range reading is displayed
below the aiming circle.
• Once a range has been acquired, you can release the Fire button. The four "crosshairs" just outside the aiming circle will go out, indicating the laser is no longer transmitted. The
display will remain on and display the last distance measurement for about 15 seconds until the display automatically switches off to extend battery life.
• You can press the Fire button again at any time to check the range to a new target. To re-fire, press the button again.
• To scan the laser across an area and get continuously updated range readings, continue to hold the Fire button down and sweep the ranging binocular over multiple targets. The
crosshairs outside the aiming circle will flash to indicate scan operation.
FOCUS AND DIOPTER ADJUSTMENT
• First, adjust the eyecups and IPD as described in the previous sections.
• Using the attached lens cap or your hand, cover the objective lens on the right side of the ranging binocular.
• Using the center focus knob, focus on a distant object with fine detail (e.g., brick wall, tree branches, etc.) until it appears as sharp as possible when viewed through the left side
of the ranging binocular.
• Uncover the objective lens on the right side, and cover the left objective lens while viewing the same object.
• Rotate the diopter adjustment ring located directly below the right eyecup, NOT the center focus knob, to bring the object into focus on the right side of the ranging binocular.
• Avoid over-turning or forcing the diopter mechanism. If you cannot bring the object into focus for your right eye by adjusting the diopter ring, make sure the left side is still in
focus (repeat steps #2-4 if necessary). The diopter adjustment essentially provides "fine focus" on one side of the ranging binocular (right only) to allow for slight differences in
the vision of your left and right eyes.
• Your ranging binocular should be adjusted for your eyes. Focusing for any distance can now be done simply by turning the center focus knob. Make a note of your diopter setting
(position of plus and minus marks on diopter ring relative to index mark on binocular below the ring) for future reference if the ring is moved accidentally or by another person
using your ranging binocular.
