damage to your eyes.

please read the following instructions carefully.

Adjusting to obtain a single picture. To adjust the
binoculars to match the spacing of your eyes simply
rotate the two sides of the instrument around the centre
hinge until a single rounded picture is obtained when
looking through both eyepieces.

Adjusting for maximum sharpness (focusing). Marine-3
binoculars feature individual eyepiece focusing but the
large depth of field generated by the 7x50 specification
means they deliver focused images from approximately
50 metres to infinity distance. As a rule for general
observation over 50 metres, the binoculars can be ‘set’
with the zero marks on the eyepiece tubes positioned
directly above the vertical line marks on the main body.

Focusing at close range (below 50 metres) is facilitated
by turning the left and right eyepieces simultaneously
anticlockwise.

Adjusting for differences in visual acuity. Some people
have differences in strength or visual acuity between
their eyes. To compensate for this the eyepiece tubes can
be rotated to different positions (usually within a few
degrees of each other) for any given distance.

Wearing glasses. Marine-3 binoculars deliver full field of
view with or without glasses. To ensure the maximum
available field of view is obtained, the fold down rubber
eyecups fitted to each eyepiece housing should be in the
‘down’ position when viewing with glasses. Be sure to
return the eyecups to the ‘up’ position if you or anybody
else wants to view without glasses.

Care and cleaning. Marine-3 binoculars require little
maintenance but occasionally the outside surfaces of the
eyepieces and objective lenses will need cleaning. To
avoid damaging these surfaces please read the following
carefully.
(i) Gently remove excess dirt and dust using a

compressed air device or blower brush. Caution:
Hard and persistent rubbing of dirty surfaces can
cause abrasive scratches on the surface of the glass
which may distort viewing.

(ii) Breathe on exposed glass surface and then wipe with

an optical cleaning cloth (code 30277) in a circular

motion until the surface is clean again.
Do not attempt to dismantle the instrument as this will
invalidate the guarantee.

We hope you will get a great deal of pleasure from your
new Opticron binocular. If you have any problems or
damage the instrument in any way our Service
Department is on hand to help you.
