What to do if Furuno FSV-35 shows weak echoes?
If you are seeing weak echoes on your Furuno Sonar, consider the following: • The output power may be set to minimum. To fix this, set [TX Power] to maximum in the [TX/RX Setting] menu. • Excessive TVG may be the issue. Readjust TVG on the [Gain Setting] menu. Note that readjustment of TVG is necessary after the gain is adjusted.
Why does my Furuno Sonar display somewhat strange color?
If the color on your Furuno Sonar appears somewhat strange, the brilliance setting may be too low. Try increasing the brightness of the monitor.
