Marine life on the transducer face will 
result in a gradual decrease in 
sensitivity. Check the transducer face 
for cleanliness each time the boat is 
dry-docked. Carefully remove any 
marine life with a piece of wood or 
fine-grade sandpaper. 
 

The fuse in the power cable protects the 
system from reverse polarity of the 
power supply and equipment fault. If the 
fuse blows, find the cause before 
replacing it. Use only a 1A fuse (FGMB

equivalent. Using the wrong fuse will 

damage the unit and void the warranty.
