Thanks for the responses. This may be a dumb question, but if my transceiver is not working, why does the plug-in (i.e. the remote that plugs into an A/C outlet) work. My understanding is that the plug-in remote also controls the transceiver. Isn't that correct?

Thanks again. I don't know much about X10 equipment. The units came with the house when I bought it.

Joe.
