EYE DISTANCE
To reach a great and contrast panorama the binoculars have to be adjusted
to the different eye distance of different users. This adjustment happens by
bending the central hinge (1) until both fields of vision of the right-hand and
left-hand telescope completely coincide during observing any object.
FOCUSING AND DEFECTIVE SIGHT ASSISTANCE
Observe any object with the left eye trough the left ocular and turn the mid-
wheel (2) till the object is clear and high contrast.
A possible defect of the eyes of ±4.0 diopters can be compensated by turn-
ing the diopter adjustment (3). Thereby observe the same object with the
right eye and turn the diopter setting wheel till the object impression is clear
and high in contrast.
DISTANCE ADJUSTMENT
To observe an object at different distances both clearly and in high contrast
it is useful to adjust binoculars to a special distance. While observing the
object the midwheel (2) has to be turned right or left till the clearest and
richest in contrast vision is reached. An adjustment of the Focusing and
defective sight assistance is not necessary.
EYE PIECE ADJUSTMENT
The binoculars are models for spectacle wearers. Normal sighted people
employ the binoculars with twist-up eyecups. Wearer of glasses just turn
the eyecups down to use the complete panorama of binoculars.
MAINTENANCE AND PROTECTION
Prism binoculars do not need special care, they are nearly of attendance. If
necessary the outer lens surfaces should be cleaned with a fine hairbrush
or a soft piece of cloth. Coarse dust should remove through wash or blow
before wiping. Do not use chemical solvents and keep it in dry place!
