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

cially the engine's wires. This will provide the best isolation from elec-

trical noise. If the cable is not long enough, splice #18 gauge wire onto

it.
The 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.
If you have to extend the power cable to the battery or power buss, at-

tach one end of the fuse holder directly to the battery or power buss.

This will protect both the unit and the power cable in the event of a

short. It uses a 3-amp fuse. 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.
Mounting The Sonar Unit: In-Dash or Bracket
You can install the sonar unit on the top of a dash with the supplied

bracket. It can also be installed in the dash with an optional dash-

mounting kit. The FM-5 mount kit will work for both the FishEasy 250

DS and SeaFinder 250 DF.
In-Dash Installation
The following figure shows dimensions for in-dash mounting. The in-

dash adapter kit includes a template for cutting the mounting hole and

complete installation directions on instruction sheet 988-0147-43.
NOTE:

Your unit needs only one cable, but some of the other products cov-

ered by the FM-5 instruction sheet use more. When installing your

unit, use the instructions for the transducer cable and ignore refer-

ences to any others.
