Why does my Furuno CH-500 picture contain noise?
If your Furuno Sonar picture contains noise, it might be due to grounding issues. Check the ground (earth) connection of the equipment. Another cause could be the power cable being too close to the signal cable; try relocating either the power or signal cable. Also, if there's debris on the sea surface, activate the [Interference] setting from the [COM1] menu.
Why are the echoes weak on my Furuno Sonar?
Weak echoes on your Furuno Sonar can be caused by the output power being set to [Low]. Change the output power to [High] from the [COM1] menu. Also, an excessively high TVG setting can cause this; adjust the TVG setting from the appropriate display mode menu. Remember to readjust TVG when you change the gain setting.
What to do if Furuno Sonar hull unit power is off?
If the Furuno Sonar hull unit is off, ensure that power is supplied to the hull unit. Check if the breaker is tripped or the fuse inside the hull unit is blown. If the power is off, turn it on and press the EVENT MARK key. Also, check the power cable connections and fasten or reconnect them if they are loose or disconnected.
Why does the seabed echo become irregular on Furuno Sonar?
Irregular seabed echoes on your Furuno Sonar can occur due to rough seas, where the distance to the seabed changes dramatically because of pitching and/or rolling. It can also happen if a long range is selected, as the long transmission period causes pitching/rolling to affect echo detection.
Why does the screen color appear strange on my Furuno CH-500 Sonar?
If the screen color appears strange on your Furuno Sonar, the brilliance setting may be too low. Adjust the brilliance.
What to do if there is water leakage from the Furuno CH-500 hull unit’s shaft flange?
To address water leakage from the hull unit’s shaft flange on your Furuno Sonar, wipe the area dry and inspect around the gasket retaining plate. If water leaks from the retaining plate, tighten the bolts.
