Fishfinder 400C Owner's Manual
Caring for the Fishfinder 400C
The case is constructed of high-quality materials and does not
require user maintenance, except cleaning.
Cleaning the Case
Clean the unit's outer casing (except for the screen) using a cloth
dampened with a mild detergent solution and then wipe dry. Avoid
chemical cleaners and solvents that may damage plastic components.
Cleaning the Screen
The unit's lens is coated with a special anti-reflective coating that
is sensitive to skin oils, waxes and abrasive cleaners. Cleaners
containing ammonia, alcohol, abrasives, or anti-grease detergents
will harm the anti-reflective coating. It is important to clean the lens
using an eyeglass lens cleaner (that is specified as safe for anti-
reflective coatings) and a clean, lint-free cloth.
Water Immersion
The unit 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 unit. After submersion, be
certain to wipe and air dry the unit before reuse.
