Lowrance 7200c 操作指南

If possible, keep the power cable away from other boat wiring, especially 

the engine's wires. This will provide the best isolation from electrical 

noise. If the cable is not long enough, splice #18 gauge wire onto it. 
The display power cable has two wires, red and black. Red is the positive 

(+) lead, black is negative (–) or ground. Make sure to attach the in-line 
fuse holder to the red lead as close to the power source as possible. 
For example, if you have to extend the power cable to the power bus or 

battery, attach one end of the fuse holder directly to the power bus or 

battery. This will protect both the unit and the power cable in the event 

of a short. 
This unit has reverse polarity protection. No damage will occur if the 

power wires are reversed. However, the unit will not work until the 

wires are attached correctly.
