Cleaning and Storage
The Fishfi nder 320C is constructed of high quality materials and does not require user maintenance other
than cleaning. Clean the unit using a cloth dampened with a mild detergent solution and then wipe dry. Avoid
chemical cleaners and solvents that may damage plastic components.
WARNING: The Fishfi nder 320C lens is coated with a special anti-refl ective coating which is
very sensitive to skin oils, waxes, and abrasive cleaners. CLEANERS CONTAINING AMMONIA
WILL HARM THE ANTI-REFLECTIVE COATING. It is very important to clean the lens using
an eyeglass lens cleaner which is specifi ed as safe for anti-refl ective coatings and a clean,
lint-free cloth.
Do not store the Fishfi nder 320C where prolonged exposure to temperature extremes may occur (such as in
the trunk of a car) as permanent damage may result. Unit settings will be retained in the unit' s memory without
the need for external power.
