in spite of the longer wire distance. For runs of 20 to 35 feet (6 to

10.6 m), use #14 AWG.

If you extend the power wiring, be sure all electrical connections are

solid and durable. Soldering is the best way to make these connec-

tions. Insulate all connections using heat-shrink tubing or electrical

tape. You may also use crimp connectors or a terminal strip, but be

sure to use good-quality marine-grade parts.

7. At the rear of the display unit, plug in the power wires using the keyed

connector.

8. When you press the

PWR

button, the display unit should turn on. If

the unit will not turn on and you suspect that you may have reversed the

power connections, check the DC power lines all the way back to the

battery. If the polarity is not correct, reconnect the leads properly and

try again.

Calibrating the Sensors

The transducer most often used with this unit includes sensors for boat

speed and water temperature. These sensors are normally very accurate,

but you may want to calibrate them. The procedure appears in the section

on the System Setup Menu (page 55).

The speed indication on your FishFinder is usually very accurate. How-

ever, there are some special cases where the speed reading may be high

or low. This means that the speed of the water past the transducer may

not be the same speed that your boat moves through the water. The hull of

the boat may have a shape which channels water past the transducer at a

speed which is faster or slower than normal.

1. To calibrate the speed sensor, set up a course between two known

points. As markers you can use buoys, range markers, or landmarks.

Measure the length of time the boat takes to cover a known distance.

2. You may also use locations indicated by a G.P.S. or Loran unit. (If you

choose this method, remember that these devices measure “speed

over ground” or “speed over the bottom.” Tides, currents, or winds

can create a difference between the FishFinder’s “speed through

water” measurement and the boat’s “speed over ground.” Before

calibrating using a G.P.S. or Loran unit, wait for still water or slack tide

conditions.
