APPENDIX > CARING FOR THE FISHFINDER
Caring for the Fishfinder
The Fishfinder case is constructed of high quality materials
and does not require user maintenance except cleaning.
Cleaning the Case
Clean the Fishfinder’s outer casing (except for the screen)
using a cloth dampened with a mild detergent solution, and
then wipe it dry. Avoid chemical cleaners and solvents that
may damage plastic components.
Cleaning the Screen
The Fishfinder screen should be cleaned using a soft, clean,
lint-free cloth. Water or eyeglass cleaner can be used if
needed. If these are used, apply the liquid to the cloth and
then gently wipe the screen with the moistened cloth.
WARNING: The Fishfinder screen is coated with a
special anti-reflective 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 screen using an eyeglass lens cleaner which is
specified as safe for anti-reflective coatings and a clean,
lint-free cloth.
Storage
Do not store the Fishfinder where prolonged exposure to
temperature extremes may occur (such as in the trunk of a
car), because permanent damage may result.
Water Immersion
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, be certain to wipe and air dry
the Fishfinder before reuse.
