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 binocu-
lars should be stored dry!
