Maintenance Tips
-
Clean lenses carefully: Use a microfiber cloth and lens-safe cleaner to protect HD coatings and maintain sharp, bright images.
-
Use lens covers: Keep objectives and eyepieces protected from dust, dirt, and scratches when not in use.
-
Avoid touching glass: Fingerprints can reduce clarity and light transmission—handle by the body only.
-
Maintain focus wheel & diopter: Keep controls free of grit for smooth focusing and accurate eye adjustment.
-
Check hinge tension: Ensure interpupillary distance stays firm for stable, comfortable viewing.
-
Dry after exposure: Even though waterproof and fogproof, wipe down after rain or humidity.
-
Store properly: Keep in a cool, dry place using a protective case for long-term durability.
-
Avoid impacts: Rubber-armored housing is rugged, but minimizing drops helps preserve optical alignment.
