Leica 40253 Ultravid BR Binoculars Instructions

Leica 40253 Ultravid BR Binoculars

Possible applications

• The Leica Ultravid binoculars have hermetic-ally sealed and nitrogen-filled magnesium housings. They are therefore suited for rough outdoor use.
• There is no need to be concerned with moisture as they are 100% waterproof to a depth of 5m and the internal optical system is not subject to fogging.
• Attaching the carrying strap and the protective eyepiece cover See illustration on the rear cover flap.
• If you want to attach the protective eyepiece cover to the carrying strap, this must be done while attaching the carrying strap to the binoculars.

Attaching the protective lens caps

To attach the caps, their rubber ring is pulled over the binoculars from the lens side (image A). When the caps are swung open, the rub-ber ring rotates, thus fixing the caps in an open position.

Adjusting the eyecups / Use with and without glasses

The eyepiece cups (1) can be easily adjusted by turning them and they lock securely into the selected positions. They can also be completely removed for thorough cleaning. For viewing with eyeglasses (image A) they remain in the fully screwed-in position. For viewing without eyeglasses, they are un-screwed by turning them anticlockwise. Two positions are available for optimum adjustment (images B, C). If the eyepieces are very dirty, it is recommended to remove the cups for cleaning (image D). To do this, they are simply pulled off while in the fully unscrewed position.

Adjusting the eye base

To set the eye base, adjust the binoculars at the hinged joint. The left and right fields of view must merge and produce a single circular image.

Focusing / Diopter adjustment

• With the Leica Ultravid binoculars, the central focusing ring (4) is used to set the focus for variously distant objects.
• Compensation for an 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 affects 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.

Notes

• The diopter ring rotates freely, i.e. 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 of 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 peo-ple 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 eyes.

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. To remove fingerprints 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. If the binoculars, particularly the rotating eyecups, are very dirty, simply rinse them under a running faucet. Always rinse off the saltwater.
Moisture inside the central focusing unit (visible through the scale window) will dry quickest when the two rings (3/4) are unlocked.
Attention!
Do not apply too much pressure when wiping strongly soiled lens surfaces. Even though the coating is very tough, sand and salt crystals can cause scratches.
