DIOPTER SETTING

FOCUSING

1. Adjust interpupillary distance. (Figure 1)

2. Set the “diopter setting” (Figure 2) to zero and view a distant object.

3. Keep both eyes open at all times.

4. Using a lens cover or your hand, cover the objective (front) lens of the same side of the binocular that has the “diopter setting.” This is usually the right side.

5.Using the center focus wheel, 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 diopter side, cover the other objective lens, then view the same object.

7.Using the “diopter setting” adjustment ring, focus the same object being viewed. Caution should be used as over turning or forcing the diopter eyepiece can cause damage or cause the eyepiece to break away from the chassis.

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.

INSTRUCTIONS FOR CARE OF BINOCULARS

Your Bushnell binocular will provide years of trouble-free service if it receives the normal care you would give any fine optical instrument. Non-waterproof models should not be exposed to excessive moisture.

1.If your binocular has roll-down, flexible eyecups, store it with the eyecups up. This avoids excessive stress and wear on the eyecups in the down position.

2.Avoid banging and dropping.

3.Store in a cool, dry place.

4.CAUTION: Looking directly at the sun with your binocular may be very harmful to your eyes.

5.Never expose your ImageView binocular to any type of excessive of liquid or fluid, as the binocular is not water/fogproof.

6.Take the batteries out of your ImageView if you are not going to use it for a long period of time. (Make sure you download any pictures from your camera before you remove the batteries from the camera.)

CLEANING

EYECUPS (Figure 3)

Your Bushnell binocular is fitted with rubber roll-down eyecups designed for your comfort and to exclude extraneous light. If you wear sun/eyeglasses, roll down the eyecups. This will bring your eyes closer to the binocular lens thus providing improved field of view.

ROLL-DOWN EYECUPS

1.Blow away any dust or debris on the lens (or use a soft lens brush).

2.To remove dirt or finger prints, 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. A “microfiber” cleaning cloth (available at most photo dealers) is ideal for the routine cleaning of your optics.

3.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.
