BINOCULAR INSTRUCTIONS
Your Bushnell binocular is a precision instrument designed to provide many years of pleasurable viewing. This portion of the booklet will help you achieve optimum performance by explaining how you can adjust the binocular to your eyes, and how to care for this instrument. Read the instructions carefully before using your binocular.

EYE ADJUSTMENTS (Figure 1)
How to Adjust For Distance Between Your Eyes
The distance between the eyes, called “interpupillary distance,” varies from person to person. To achieve perfect alignment of lens to eye, follow these simple steps.
1.Hold your ImageView in the normal viewing position.
2.Holding the ImageView at the grip areas (dots and ridges on top
and bottom surfaces), carefully slide the left and right sides apart until it is set for your eye spacing (you will see a singular circular field). If you go too far, simply slide the sides back so they are closer together. Note the index scale position to help you reset this if someone else uses your ImageView.
How to Adjust For Individual Eye Strength
As individual eyesight varies from one person to another, Bushnell binoculars have a diopter setting feature which allows you to
FOCUSING
1. Adjust interpupillary distance. (Figure 1)
2.Set the “diopter setting” (the dial on the bottom front of the ImageView ) to zero (the middle mark on dial - opposite arrow) and view a distant object. (Figure 2)
3.Keep both eyes open at all times.
4.Using your hand, cover the objective (front) lens on the right side.
5.Using the center focus wheel (on the bottom of binocular
between the eyepieces), focus on a distant object with fine detail (e.g., brick wall, tree branches, etc.) until it appears as sharp as possible.
6.Uncover the objective lens on the right side, cover the other objective lens, then view the same object.
7.Using the “diopter setting” dial, focus the same object being viewed. Caution should be used as over turning or forcing the dial can cause damage.
8.Your binocular should be adjusted for your eyes. Focus at any far or near distances can now be attained simply by turning the center focus wheel. Make a note of the diopter setting for your eyes for future reference.
