Troubleshooting
Unit doesn’t power up.
a) Check the cable connection and wiring. Make sure the cable is properly connected to
the Fishfinder and the batteries are charged.
b) Make certain the batteries voltage is not lower then the warning value (10 V)
Weak Bottom Echo, Unstable Depth Reading, or No Fish Signals.
a) Make certain the transducer is installed properly.
b) Extremely heavy vegetation may confuse the sonar signal, causing it to misinterpret
the depth. If you are certain that the readings are incorrect under these conditions,
discontinue use.
c) Oil, dirt and fuel might cause a film to form on the transducer and reduce its
effectiveness. Cleaning the face of the sensor might help.
d) Please check the battery charge. The unit's transmitter power will decrease due to the
voltage drop. And this will reduce its ability to find the bottom or targets.
e) The sonar might be in turbulent water. Mounting it in a smooth flow of water might help.
Bottom disappears, suddenly weakens, when the boat moves at high speed
a)
The sonar might be in turbulent water. See the installation guide and adjust the
transducer position to a smooth flow of water.
Nothing appears on the display even you can see fish under the transducer.
a) Check the transducer installation to make certain it is properly installed. An improper
installation may cause sonar signal
lost.
b) Oil, dirt and fuel might cause a film to form on the transducer and reduce its
effectiveness. Cleaning the surface of the transducer might help.
The display become so cluttered that you even could not achieve a clear bottom
a) Such cluttered display maybe caused because:
a) The water is too low
b) The water is too turbid
c) There are so much debris in the water,
b) Increasing the Noise Reject to 8 or a bigger value will be helpful
