Insteon SwitchLinc 2476S Hums when off

As title says, my switches all hum when off, humming goes away when they are switched on! Does anyone have similar problems, if so any ways to alleviate the issues.

Are the switches the newer Rev 5.0 or higher?
I don't recall any hum on my older revision modules; but I will go and listen just to make sure.
Smartlabs has changed things in the newer hardware. I believe an isolated load and sensing was added to the new ones.

There was a similar problem reported in the Smarthome Forums.
You may want to try disconnecting the load and see if it hums all by itself. Guess the Isolated Load wire connected to the Line would be a good choice.
