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. If you have any
problems or damage the binocular in any way our
Service Department is on hand to help you.
Care and cleaning
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.
Cold weather
In cold weather the external lens surfaces may steam
up when moving the instrument from cooler air
outside to warmer air inside. If this occurs, leave
the instrument to stand for a few minutes until any
condensation evaporates.
until the object being viewed becomes sharp. Push
down dioptre adjustment wheel to lock in position.
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.
Rubber Eyecups 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 binocular.
Wearing glasses
Opticron Countryman BGA binoculars are designed
to provide the full field of view when wearing
glasses. To maximise field of view with glasses on,
twist down the eyecup assemblies - remembering to
return them to the upright position if you or anybody
else wants to use them without glasses.
Binoculars 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
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.
Adjusting for maximum sharpness
Many people have slightly different vision between
their eyes. When using binoculars, this difference
can be easily compensated for by setting the dioptre
adjustment located above the focusing wheel.
To set the binoculars correctly, close your right eye
and look through the left eyepiece with your left eye
and 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 pulling out and rotating the dioptre adjustment
wheel (but without turning the centre focus wheel)
