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 ± 3,0 dioptres can be compensated by turning the
dioptre 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.
