Opticron DBA Oasis - Manual (Page 5)

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.
