Hello...

I just bought & installed  new S515 switch into a 4-way circuit in the US.

On restoring power to the circuit, the indicator light is flashing amber, and the switch is clearly cycling on and off, constantly clicking.

I have cycled power to the circuit,  pressed the Restart button for 10+ seconds (stopped flashing but immediately resumed), and pressed the Reset button for 5+ seconds (no result at all).

Can anyone suggest some troubleshooting steps?
