Di-ffamp working or not

[Nedda]

Hi I have a Di-ffamp connected to the TZT3 16” with a 165T/PM542LM transducer. how do I know the system is working correctly.
There are two lights in the di-ffamp control box, when I turn it on, I have a solid green light and the other light is green and flashing. Is this a correct working state.

The DI-FFAMP is simply an amplifier. Those lights are indicating that it's working. Also, if it wasn't working, you wouldn't have the option to select the PM542LM from the transducer selection menu...anything above 1kW would not appear or be selectable.
