INDICATIONS ON THE SCALE
As long as the two halves of the drive are cou­
pled 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
people 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 eye.
