Opticron DBA Oasis S-Coat Mg - Manual (Page 5)

Retractable rubber eyecups and wearing glasses. Opticron DBA
binoculars provide the full field of view when wearing glasses. To get
the maximum field of view with glasses on, turn the eyecup clockwise
into the ‘down’ position. Remember 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 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 (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 happens, 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 Opticron DBA binocular. If you have any problems or
damage the instrument in any way please contact our Service Department.
