Your GPSMAP 620 contains sensitive electronic components that 

can be permanently damaged if exposed to excessive shock or 

vibration. To minimize the risk of damage to your GPSMAP 620, 

avoid dropping your unit and operating it in high-shock and high-

vibration environments.

The GPSMAP 620 is constructed of high-quality materials and 

does not require user maintenance other than cleaning. Clean 

the outer casing of the unit (not the touchscreen) using a cloth 

dampened with a mild detergent solution, and then wipe it dry. 

Avoid chemical cleaners and solvents that can damage plastic 

components.

Clean the touchscreen with a soft, clean, lint-free cloth. Use water, 

isopropyl alcohol, or eyeglass cleaner, if needed. Apply the liquid 

to the cloth, and then gently wipe the touchscreen.
