transfer from the hands through the casing to the cold
air trapped inside. Try to avoid this by using gloves and
leaving the instrument to stand when transferring from
a cool to a warm environment.
Opticron rainguard (binoculars)
A rainguard will help protect the eyepieces from rain,
snow, dust and accidental damage when in use. If your
binoculars are not supplied with a rainguard, you may
be able to purchase one to suit by contacting us at the
address overleaf.
WARNING
Never under any circumstances use a binocular to
view the sun. Doing so will cause serious damage to
your eyes.
We hope you will get a great deal of pleasure from
your new Opticron binocular or monocular. If you
have any problems or damage the instrument in any
way our Service Department is on hand to help you.
maximum available field of view is obtained. Be sure
to return the eyecups to the ‘up’ position if you or
anybody else wants to view without glasses.
Care and cleaning
Binoculars and monoculars 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.
Cold weather
In cold weather, equipment not hermetically sealed
and filled with nitrogen may steam up due to heat
using the centre focus wheel - focus on an object of
your choice until it is clear and sharp. Next, close your
left eye and look through the right eyepiece with your
right eye. You may find the object being viewed is not
absolutely sharp and this can be corrected by rotating
the right hand side adjustment ring or eyepiece (but
without turning the centre focus wheel) until the object
being viewed becomes sharp. The binoculars are now
set and a perfectly clear and sharp image should be
attainable when using both eyes together. To focus at
different distances simply rotate the centre focus wheel.
For ‘independent eyepiece focus’ binoculars, usually
7x50 Marine binoculars without a centre focus wheel,
focusing at close range is facilitated by turning the left
and right eyepieces simultaneously.
Wearing glasses
Many Opticron binoculars and monoculars are
designed to offer you the full field of view when
wearing glasses. The rubber eyecups fitted to these
instruments are designed to position your eyes correctly
to get the maximum comfortable field of view with or
without glasses and are often unique to each individual
model. If the eyepieces have a fold down or retractable
eyecup they should be used in the ‘down’ position
when viewing with glasses. Doing this will ensure the
A binocular or monocular can be a useful companion
when travelling, going to sporting and leisure events or
used as part of a hobby such as birdwatching or
astronomy. To help you get the best results from your
equipment please read the following instructions
carefully.
Adjusting to obtain a single picture (binoculars)
To adjust to the spacing of your eyes simply rotate the
two sides of the binocular around the centre hinge
until a single rounded picture is obtained when looking
through both eyepieces. Some roof prism binoculars
have two hinges and a single rounded picture is
obtained by rotating both hinges simultaneously
around the centre focusing plate.
Adjusting for maximum sharpness (binoculars)
Many people have slightly different vision between
their eyes. When using binoculars, this difference can
be easily compensated for by setting the single
eyepiece adjustment located on the right hand side of
the binocular below the eyepiece or on the eyepiece
itself. The marks on the housing show the difference in
visual acuity between your eyes on a dioptre scale.
To set the binoculars correctly , close your right eye and
look through the left eyepiece with your left eye and
