NFORMATION

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. 

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.) 

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.
