Garmin 278 Manual De Propietario

The GPSMAP 278 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 GPSMAP 278 screen should be cleaned using a soft, clean, lint-

free cloth. Water, isopropyl alcohol, 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.

Do not store the GPSMAP 278 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 PC 

(transferring it to MapSource).

The GPSMAP 278

 

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 or 

charging.
