CARE/CLEANING
Your Leica Digiscoping Adapter has been designed for constant use
outdoors. No particular care is needed other than occasional
cleaning. Fingerprints, droplets of water, etc. on external lenses can
be wiped off using a soft, lint-free cloth. Breathing on the lenses
beforehand may help. Coarse soiling on the glass surfaces, such as
sand, should be removed using a fine brush or blown off. In the case
of severe soiling, the binoculars may be cleaned by rinsing them
under running water that is hand-hot at most. Salt water should also
be washed off. Alcohol or other chemical solutions may not be used
for cleaning.
