Test and Finish the Transducer Installation
When you have installed both the control head, the transducer, and
accessories and have routed all the cables, you must perform a final test
before locking the transducer in place. Testing should be performed with the
boat in the water, although you can initially confirm basic operation with the
boat out of the water.
1. Press the POWER/LIGHT key once to turn the control head on. There
will be an audible chirp when the key is pressed correctly. If the unit
does not power-up, make sure that the connector holder is fully
seated and that power is available.
2. If all connections are correct and power is available, the control
head will enter Normal operation. If no transducer is detected (or
one is not connected), the unit will go into Simulator mode and will
indicate this by displaying the word Simulator on the control head
display.
NOTE: The transducer must be submerged in water for reliable transducer
detection.
3. If the bottom is visible on-screen with a digital depth readout, the
unit is working properly. Make sure that the boat is in water greater
than 2 ft (.6 m) but less than the depth capability of the unit, and
that the transducer is fully submerged, since the sonar signal
cannot pass through air.
4. If the unit is working properly, gradually increase the boat speed to
test high-speed performance. If the unit functions well at low
speeds but begins to skip or miss the bottom at higher speeds, the
transducer requires adjustment. Angling the rear of the transducer
downward and/or lowering the transducer farther into the water
will help achieve depth readings at high speeds. If the left side of
the fish arch is longer than the right side, then the back of the
transducer is angled too far downward. If the right side of the fish
arch is longer than the left side, then the back of the transducer is
angled too far upwards.
NOTE: It may not always be possible to get symmetrical fish arches and high
speed depth readings at the same time. Due to the wide variety of boat hulls,
however, it is not always possible to obtain high speed depth readings.
NOTE: It is often necessary to make several incremental transducer adjustments
before optimum high speed performance is achieved.
Once you have reached a consistently good sonar signal at the desired
speeds, you are ready to lock down the transducer settings.
5. Mark the transducer bracket location on the transom with a pencil,
then pop up the bracket to reveal the mounting screws. Tighten the
stainless steel mounting bracket screws to secure in place.
