Operation and settings
Adaptation of the eye cups
NOBILEM models (except NOBILEM – Navidoc) are equipped with protective eyecups
(1) whose use assist those wearing glasses and who are emmetropic to use the whole
field of view of the binoculars. Those wearing glasses turn the eye cups over at (2) and
thus achieve the correct ocular – eye-distance. Persons who are emmetropic or who
wear contact lenses leave the eye cups in their erect position (3)
Setting the eye spacing
In order to achieve the largest possible circular picture the binoculars must be set to the
individual eye spacing. Take the binoculars in both hands and turn the middle joint (4) of
the binoculars while looking through it until the picture is sharp and circular. The tight
setting of the middle joint at the works prevents the inadvertent movement of the eye
spacing while carrying and watching. An eye-side graticule marking allows the user to
recognize the setting.
