WARNING Never look at the Sun while using your binocular. Looking at the Sun can cause permanent eye damage. Adjusting the Interpupillary Distance The interpupillary distance, or the distance between the pupils, varies from person to person. The binocular must be correctly aligned (adjusted) to the distance between your pupils to achieve a single, clear image. To adjust this distance, lift the binocular up to your eyes (using both hands) and look through them at an object in the distance. Move the two barrels (halves) of the binocular closer together or further apart until you see a single, clear image (Fig. 2). Check that the interpupillary distance is set correctly every time you use your binocular. Fig. 2 Setting the Diopter / Focusing To ensure a crisp, sharp image, the binocular's focusing system must be set to compensate for any differences in your eyesight. This is achieved by setting the diopter (located on the right eyepiece) before use. To set the binocular to your eyesight follow the instructions below. 1. View an object in the distance through the binocular. 2. Cover the right objective lens with your hand or the objective lens cap. 3. Rotate the focus wheel until the image viewed with your left eye is clear and sharp. 4. Cover the left objective lens with your hand or objective lens cap. 5. Viewing the same object, adjust the diopter ring until the image viewed with your right eye is clear and sharp. Diopter Adjustment Ring Focus Wheel Fig. 3 3
