MAINTENANCE / REPLACING THE BATTERY POWER CABLE
MAINTENANCE
Your Humminbird Portable fishfinder is designed to provide years of trouble-free operation with
virtually no maintenance. Follow the simple procedures below to ensure that your Humminbird
Portable continues to deliver top performance.
If you are storing the Portable case for an extended period of time, it is best to remove the bat-
teries from the case in case of leakage.
If the Portable case comes into contact with salt spray, simply wipe the affected surfaces with a
cloth dampened in fresh water.
Never leave your Humminbird Portable unit in a closed car or trunk - the extremely high tem-
peratures generated in hot weather can damage the electronics. Repairs should be performed
only by authorized Humminbird technicians.
