Caring for the GPSMAP 378/478

The GPSMAP 378/478 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 GPSMAP 378/478 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.

Storage
Do not store the GPSMAP 378/478 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).

Water Immersion

The GPSMAP 378/478 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.
