Using the binoculars with and without
spectacles
If you do not wear glasses, pull out the eyecups
and telescopic eyepiece tubes to the click stop.
This places your eyes at the correct distance
from the eyepiece lens. The click stop ensures
firm positioning of the binoculars.
If you wear glasses, push in the eyepiece tubes.
This allows you to see the full field of view with-
out vignetting at the edges.
Eyebase
To set the eyebase, adjust the binoculars at the
hinged joint. The left and right visual fields must
merge and produce a single circular image.
