Introduction

Caring for Your GPSMAP 640

Your GPSMAP 640 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 640,
avoid dropping your unit and operating it in high-shock and high-
vibration environments.

Cleaning the Unit

The GPSMAP 640 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.
Cleaning the Touch Screen
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.

Protecting Your GPSMAP 640
• Do not store the GPSMAP 640 where prolonged exposure to
extreme temperatures can occur, because it can cause permanent
damage.
• Although a PDA stylus can be used to operate the touchscreen,
never attempt this while operating a vehicle. Never use a hard or
sharp object to operate the touchscreen because damage might
result.

Water Immersion

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.

Avoiding Theft

• To avoid theft, remove the unit and mount from sight when not
in use.
• Do not keep your unit in the glove compartment.
