Loosen the eyecup cuff tension knob
«IMPORTANT: always be certain the eyecup
cuff tension knob is sufficently loosened before
attempting to remove the adapter from the
binoculars’ eyepiece.
Fit the eyecup cuff over the eyecup of the
binocular and tighten the eyecup cuff tension
knob until the adapter is held firmly in place
Loosen the smartphone clamp position knob (if
not already loose) and position the eyecup of
the adapter so that its aperture aligns with the
camera lens of the smartphone
Tighten the smartphone clamp position knob
and check that the position of the adapter’s
eyecup aperture stays centered over the
smartphone camera lens
Activate the smartphone camera and check
that the image seen through the binocular is
centered in the smartphone’s viewing screen. If
it is not, use the adapter’s clamp position knob
to make adjustments until it is.
NOTE: the image will be vignetted (shows as a circle
inside a black border area - this is normal. Simply use
the smartphone camera’s zoom to expand the image
until the vignetting disappears.
Pull outward on the spring clamp arms and place
the smartphone into the space between the
clamp arms so that it is securely grasped by the
tension of the arms.
