MAINTENANCE AND CARE
The spotting scope requires no special care, it is 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
device should be stored dry! In addition, it is always recommended to use
the eyepiece protective cap and the lens protective cap after use.
Furthermore, the ever-ready case included in the scope of delivery serves
for safe storage as well as for use, due to the easy disassembly possibility of
the eyepiece protection and objective lens protection.
