Care Information
Cleaning the Unit
The GPSMAP 188/188C Sounder is constructed of high quality
materials and does not require user maintenance other than
cleaning. Clean the unit using a cloth dampened with a mild
detergent solution and then wipe dry. Avoid chemical cleaners and
solvents that can damage plastic components.
Storing the GPSMAP 188/188C Sounder
Do not store the GPSMAP 188/188C Sounder where prolonged
exposure to temperature extremes can occur (such as in the trunk
of a car) as permanent damage can 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.)
Immersing the Unit in Water
The GPSMAP 188/188C Sounder 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.
