Why is the speed/water temperature readout unrealistic or not present on my Furuno Fish Finder?
If the speed/water temperature readout is unrealistic or not present on your Furuno Fish Finder, check the sensor plug.
Why is the position readout unrealistic or not present on my Furuno FCV-627 Fish Finder?
If the position readout is unrealistic or not present on your Furuno Fish Finder, check the connection between the fish finder and the navigator, and also check the navigator itself.
Why is my Furuno FCV-627 sensitivity so low?
Low sensitivity on your Furuno Fish Finder can be caused by several factors. Check the gain setting. Ensure that air bubbles or marine life are not clinging to the transducer face, and that sediments are not present in the water. Also, the bottom may be too soft to return an echo.
What to do if my Furuno FCV-627 Fish Finder screen is blank?
If the screen on your Furuno Fish Finder is blank, try adjusting the brilliance.
Why is there extreme interference or noise on my Furuno FCV-627 Fish Finder?
Extreme interference or noise on your Furuno Fish Finder may occur if the transducer is too close to the engine. Ensure the unit is properly grounded. Also, check if other echo sounders of the same frequency are being operated nearby.
What to do if neither echo nor fixed range scale appears on Furuno FCV-627 Fish Finder?
If neither the echo nor the fixed range scale appears on your Furuno Fish Finder, check the battery voltage, the fuse, and the power cable assembly.
What to do if no echo appears but the fixed range scale appears on Furuno FCV-627?
If no echo appears but the fixed range scale is visible on your Furuno Fish Finder, check if the display advance speed is not set to [Stop]. Also, check the transducer plug and the transducer cable.
What to do if echo appears but zero line does not on Furuno FCV-627?
If the echo appears but the zero line does not on your Furuno Fish Finder, verify if range shifting is set to '0'. Also, check if zero line rejection is 'Off'. The draft setting should be other than '0'.
Why is the sensitivity low on my Furuno FCV-627?
The sensitivity might be low due to the gain setting, air bubbles or marine life clinging to the transducer face, sediments present in the water, or the bottom being too soft to return an echo. Check these potential causes to improve sensitivity.
What to do if there is extreme interference or noise on Furuno FCV-627 Fish Finder?
If you're experiencing extreme interference or noise, check if the transducer is too close to the engine, ensure the unit is properly grounded, and verify that other echo sounders of the same frequency are not being operated nearby.
