MAINTENANCE AND CARE

The prism binoculars require no special care, they are virtually maintenance-
free. Optic external surfaces must be cleaned with a fine brush or a soft
cloth if necessary. Coarse dirt particle should be rinsed off or blown off
before wiping. An excessive rubbing when brushing the optical parts can
destroy the anti-reflection coating. No chemical solvents should be used and
the binoculars should be stored dry!
