6. Maintenance and Care

6.1. Cleaning the Lenses

The rangefinder features multi-coated lenses with hard, hydrophobic, anti-radiation, and anti-reflective coatings for durability and clear vision. To clean them:

• Gently wipe the lenses with a clean, soft microfiber cloth.
• For stubborn smudges, use a small amount of lens cleaning solution applied to the cloth, not directly to the lens.
• Avoid using abrasive materials or harsh chemicals, as these can damage the coatings.
