Using one of the rings, then focus the respec
tive barrel on the desired subject. Continue
by setting the optimal focus for the second
barrel with the other ring. Pressing the diopter
ring back down locks the set value. The set
value can be conveniently read from the accu
rate scale on the diopter ring.

notes:
– The diopter ring rotates freely, i.e. it can
accidentally be rotated by more than 360°
with respect to the central focusing ring.
Depending on the latter's previous setting,
the combined system's focusing range can
be limited considerably by this. Therefore,
take care to turn the diopter ring only as
far as necessary for the eyesight adjust
ment.
– For viewing on just the left or the right
side, the other eye should be kept closed
or the appropriate half of the binoculars
simply covered at the front on the lens.
