The Fishfinder case is constructed of high-quality materials and 

does not require user maintenance except cleaning. 

Clean the Fishfinder’s outer casing (except for the screen) using 

a cloth dampened with a mild detergent solution. Wipe it dry. 

Avoid chemical cleaners and solvents that can damage plastic 

components.

Apply eyeglass lens cleaner to a clean, lint-free cloth, and then 

gently wipe the screen with the moistened cloth.

  CAUTION: The Fishfinder 340C lens is coated with a special 

anti-reflective coating which is very sensitive to skin oils, 

waxes, and abrasive cleaners. CLEANERS CONTAINING 

AMMONIA HARM THE ANTI-REFLECTIVE COATING. 

Do not store the Fishfinder where prolonged exposure to 

temperature extremes might occur (such as in the trunk of a car), 

because permanent damage can result. 

The Fishfinder is waterproof to IEC Standard 60529 IPX7. It can 

withstand immersion in 1 meter of water for 30 minutes. Prolonged 

submersion can cause damage to the Fishfinder. After submersion, 

wipe and air dry the Fishfinder before reusing.
