I just got my IR543 and 2 PCS Light Switches. After Installing everything the IR543 Turned the lights ON OFF Dim and Bright. I was playing around in all the different modes and trying to figure out how to set it up for use with my Pronto 2000. Now the Next day I cannot control the lights with my Pronto or IR543. Nothing at all. I tried resetting the switch but when I press all lights on 3 times or All lights off 3 times it does not work. Nothing happens. And when I press any button on the 543 the switches do not change color. Can the IR543 be bad already? Or did I mess something Up?

Any Help would be great..

Thanks

Is the unit very close to your AV stack or other electrical equipment? Apparently the IR543 is very susceptible to electromagnetic interference, so its best to distance it from other electrical items.

Apart from that, what happens when it does lock up? Does the red light still come on when sending IR to the unit?

I tried moving it to a different part of the room, Tried different outlets, and yes when I press the buttons the light does com on.
Im stumped.
I even Just went out to Radio Shack and got another IR543 but the radio Shack One and Still Nothing.

Is it the Switches?
Do I have to reset them?

Thanks

I Just want to let everyone I figured out the problem...

I was using my laptop in my theater room to program my pronto and the reason the IR543 and Lights stopped working was due to noise "i guess" coming from the Power Supply of the Laptop. I unplugged the laptop and everything worked.
Drove Me Crazy for a while, but i guess its good learning...

Thanks
