Warning notices

• Never look directly at the sun or other sources of bright light with your binoculars! This could cause eye damage!
• Never use your binoculars while you are walking! You might overlook obstacles!

Attaching the carrying strap and the protective eyepiece caps

(See illustration 1 on the rear cover flap.) If you want to attach the protective eyepiece caps to the carrying strap, this must be done while attaching the carrying strap to the binoculars.

Adjusting the eyecups / Use with and without glasses

The eyepiece cups (1) are telescopic. They can be pulled out (1a) or pushed in (1b) for viewing without or with eyeglasses, respectively.

Adjusting the eyebase

(See also illustration 2 on the rear cover flap) To set the eyebase, turn the binoculars' optical systems (5) around their hinged joints (4). The left and right fields of view must merge and produce a single circular image.

Focusing / Diopter compensation

(See also illustrations 3a/b on the rear cover flap) The focus for variously distant objects is set with the central focusing ring (2).

To compensate for individual vision defects when viewing without glasses, the button for diopter compensation (7) is used additionally.

1. Cover the right lens or close your right eye.
2. Target a distant object.
3. Set the optimum sharpness for your left eye using the focusing ring.
4. Cover the left lens or close your left eye

5. Press the diopter compensation button and then use the focusing dial to bring the same viewing point into focus for the right eye.

6. Look through both lenses in turn and check whether the left and right images are in focus at the same time. Otherwise, repeat the steps from 1. The set value can then be read on the diopter scale (2a).

Notes:

- In case of 20/20 vision or viewing with glasses, set the diopter scale to 0 ().

• If different individuals use your Leica Ultravid compact binoculars you should memorize your personal diopter scale setting. This allows you to set your personal value quickly at any time.

Care and maintenance

Your Leica Ultravid compact binoculars do not require any special maintenance. Use a soft lens brush or a blower to remove large particles of dirt, sand, etc. To remove fingerprints etc., wipe eyepiece and lens with a piece of clean, soft chamois leather or lint-free cloth. Water stains on the lens and eyepiece surfaces can be removed best with a cloth lightly moistened in water.

Attention: Do not apply too much pressure when wiping strongly soiled lens surfaces. Even though the coating is highly abrasion resistant, sand and salt crystals can cause scratches.

Replacements

If you should need replacements for your binoculars, such as eyecups or the strap, please contact our Customer Service department or your national Leica agent. The addresses are listed in the Warranty Card.
