Objective, eyepiece and prisms
• Blow dust off lenses and prisms.
• Never touch the glass with your fingers.
• Use only a clean, soft, lint-free cloth for cleaning. If necessary, moisten the cloth with water or pure alcohol. Do not use other liquids; these may attack the polymer components.
Fogging of prisms
Reflector prisms that are cooler than the ambient temperature tend to fog. It is not enough simply to wipe them. Keep them for some time inside your jacket or in the vehicle to allow them to adjust to the ambient temperature.
Damp products
Dry the product, the transport container, the foam inserts and the accessories at a temperature not greater than 40°C / 104°F and clean them. Do not repack until everything is completely dry. Always close the transport container when using in the field.
Charger and AC-adapter
Use only dry, clean, soft and lint-free cloths for cleaning.
Cables and plugs
Keep plugs clean and dry. Blow away any dirt lodged in the plugs of the connecting cables.
