Opticron Countryman BGA HD - Manual (Page 2)

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.

binoculars are now set and a perfectly clear and sharp
image should be attainable when using both eyes

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) until the
