Bushnell 118328 Adjusting the Binocular IPD, Eyecups, Setting the Diopter Adjustment

USING THE BINOCULAR

Adjusting the Binocular IPD

The distance between the eyes, called “interpupillary distance,” varies from person to person. To set the hinge to the right spacing for your eyes: Hold the binocular in the normal viewing position, with a firm grip on each side. Move the barrels closer together or further apart until you see a single circular field. Always re-set your binocular to this position before using.

Eyecups

The ImageView binocular is fitted with rubber roll-down eyecups designed for your comfort and to exclude extraneous light. If you wear glasses, roll down the eyecups. This will bring your eyes closer to the binocular lens so you can view the entire image without any cutoff.

Setting the Diopter Adjustment

1.Rotating the right eyecup (pg. 3, J) allows you to fine tune the binocular focus to your vision (diopter adjustment). Make sure the right eyecup is set to “zero” for now (arrow on the underside of the eyecup pointing to “0”). Keep both eyes open at all times.

2.Using your hand, cover the objective (front) lens on the right side of the binocular as you look into the eyepieces.

3.Turn the binocular focus knob (F), until a distant object with fine detail (e.g., brick wall, tree branches, etc) appears as sharp as possible through the left side of the binocular.

4.Uncover the objective lens on the right side, and cover the left objective lens while continuing to view the same object.
