Wearing glasses
Opticron Imagic BGA VHD 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.
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.
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.
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 single eyepiece adjustment located on the right hand side of the binocular below
the eyepiece. 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
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 (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.
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.
