User Instructions
Binoculars can open up a whole range of new and exciting
impressions when travelling on holiday, taken 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 simultaneously rotate both barrels
of the binocular around the centre focusing plate 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 turning the dioptre adjustment wheel. On DBA compact
models this wheel is located on the bottom of the main body.
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 rotating the dioptre
adjustment wheel (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 turn 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.
Using glasses. Opticron DBA binoculars provide the full field of view when
wearing glasses. To maximise field of view with glasses on, turn eyecup assembly
clockwise into the ‘down’ position - remembering to return them to the upright
position if you or anybody else wants to use them without glasses.

User Instructions
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 compressed air 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 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.
WARNING Never under any circumstances use a binocular to view the Sun. Doing so may 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.
