Description & Special Features
(cont’d)
Each telescope is comprised of
eyecups
(1) , a housing assembly
(2 or 3) and objective covers (4).
The binoculars are optically pre-
aligned at the factory and must
not be disassembled.
The friction necessary to maintain
the proper interpupillary distance
(distance between the eyes) is cre-
ated by rubber O-rings installed in
the grooves of the index pin.
Once this distance is set for your eye spacing, the reading
on the interpupillary scale
(5) can be noted for future
reference.
By rotating the knurled adapter ring
(6) of the eyepieces,
you can focus each telescope to accommodate your par-
ticular optical characteristics. The reading on each diop-
ter scale
(7) should then be noted for future reference. The
eyepiece cover (8) should be placed over the eyepieces
when the binocular is not in use.
