Congratulations on your outstanding new binoculars.
Enjoy the impressive experience of undistorted image reproduction
which is distinguished by perfect brilliance and excellent colour accuracy.
The Carl Zeiss brand is famous for outstanding optical achievements,
precision workmanship and long service life. Please observe the follow-
ing instructions for use in order to obtain the best from your binoculars
and to ensure that they remain your constant companion for many years
to come.
Viewing with and without eyeglasses
If you wear glasses when viewing, fold down the soft rubber eyecup over the
eyepiece mount as shown in Fig. 1/B, 2/B and 3/B.
If you do not wear glasses, use the binoculars with the eyecups extended as
shown in Fig. 1/A, 2/A and 3/A.
Adjustment of the interpupillary distance
Adjust the two barrels relative to each other about the central axis until you
see one circular field of view when viewing with both eyes.
Focusing
When using binoculars with a middle drive, cover the objective lens on the
right side of the binoculars and focus the image on the left side using the
middle drive (Fig. 1/2). Then cover the objective lens on the left side and –
if necessary – set the focus on the right side using the diopter adjustment
(Fig. 1/1).
For additional focusing at different distances, use only the middle drive
(Fig. 1/2).
When using binoculars without a middle drive, but with individual eyepiece
adjustment, the focus must be individually set for both eyepieces (Fig. 2/3+4
and Fig. 3/5 + 6).
