The GPSMAP 76Cx case is constructed of 

high quality materials and does not require user 

maintenance except cleaning. 

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.

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.

Do not store the GPSMAP 76Cx where prolonged 

exposure to temperature extremes may occur (such 

as in the trunk of a car) as permanent damage may 

result. User information, such as waypoints and routes 

are retained in the unit’s memory without the need 

for external power. It is always a good practice to 

back up important user data by manually recording 

it or downloading it to a computer (transferring it to 

MapSource).

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.
