Maintenance
Cleaning the lens
1
Apply a non-abrasive camera lens cleaner to a soft, dry cloth.
• Avoid using an excessive amount of cleaner, and don’t apply the
cleaner directly to the lens. Abrasive cleaners, solvents or other harsh
chemicals might scratch the lens.
2
Lightly wipe the cleaning cloth over the lens in a circular motion.
