Trouble shooting
In the event of problem during product use, we invite you to read the following trouble
shooting part carefully before you send the product for maintenance.
Nothing is displayed after the fish finder is powered.
Be sure the battery's positive and negative poles are correctly oriented in the holder.
Also, check if the battery has enough capacity.
No signal screen.
If the fish finder fails to receive signals from the sensor, it will stop updating the
screen (which will then remain unchanged).
Under any circumstances, if the sonar unit cannot receive signals transmitted by the
transducer, the screen will seem the same until signals are restored.
The deep capability is 30m and the RC distance is 300m max.
Nothing appears on the display even you can see fish under the sensor.
Oil, dirt and fuel might cause a film to form on the sensor and reduce its
effectiveness. Cleaning the surface of the transducer might help.
Electrical noise nearby can interfere with the sonar, which will cause some weaker
signals being eliminated.
The display become so cluttered that you even could not achieve a clear
bottom.
Such cluttered display maybe caused because:
- The water is too low
- The water is too turbid
- There is so much debris in the water
The sonar unit cannot reach 300m. There is an abnormal display on the
display, and when the bait boat is about 60/70m faraway, the sonar unit stop
working.
