[. . . ] 15 Adjusting the eyecups / Use with and without glasses. Warning notices Never look directly at the sun or other sources of bright light with your binoculars!Never use your binoculars while you are walking!They are therefore suited for rough outdoor use. [. . . ] Compensation for individual defective vision for viewing without eyeglasses is made using the diopter ring (4), which is normally locked (Figure A). To unlock the two rings the diopter ring is pulled up (Figure B). Now, the central focusing ring only effects the focus of the left optical system, the diopter ring only that of the right system. Using one of the rings, then focus the respective barrel on the desired subject. Continue by setting the optimal focus for the second barrel with the other ring. pressing the diopter ring back down locks the set value. The set value can be conveniently read from the accurate scale on the diopter ring. It can accidentally be rotated by more than 360° with respect to the central focusing ring. depending on the latter's previous setting , the combined system's focusing range can be limited considerably by this. Therefore, take care to turn the diopter ring only as far as necessary for the eyesight adjustment. ­ For viewing on just the left or the right side, the other eye should be kept closed or the appropriate half of the binoculars simply covered at the front on the lens. Indications on the scale As long as the two halves of the drive are coupled together, the binoculars are permanently adjusted to your eyesight, irrespective of the focusing distance to an object. You need to make the adjustment only once. If other people use your binoculars, they may have to alter the setting. Simply note your personal setting on the scale; when someone else has used them, you can reset the binoculars in a matter of seconds. The distance between two divisions on the scale represents a difference of approx. One diopter of correction being applied to the left and right eye. Care and maintenance Your Leica Ultravid binoculars need no special maintenance. Use a soft lens brush or a blower to remove large particles of dirt, sand, etc. , first wipe the eyepiece and lens with a damp cloth, then dry them with a piece of clean, soft chamois leather or lint-free cloth.
