Guys, I appreciate all of your help. let me see if I can explain/clarify further.
To start, my light bulb is incandescent.
Switch is connected in the hallway, at the entrance to the apartment.
When replacing the switch, I flipped the fuse before disconnecting the existing switch. Doing so, I noted which wall outlets were TURNED OFF as well. Now, I knew that those outlets are on the same breaker.
After connecting the x10 switch and coding it A2, I plugged in the transceiver into one of the wall outlets noted before. Transceiver coded as A1 and has a table lamp connected to it (for testing).
Now, I take the remote, (standing few feet from the RR501) and hit the FIRST button (A1). Bingo, table lamp turned ON
Now, I hit the SECOND button (A2). Bingo, hallway light goes ON.
So far, all works great. now, I would like to utilize the remote from the bedroom, which is on the other side of the Transceiver and due to the range limitation will NOT reach the RR501 (where it is currently plugged in).
So, I tried to move the RR501 to an outlet in the bedroom.
the Table lamp, connected to the RR501, still continues to work, but NOW, the switch in the hallway DOES NOT.
I also tried to put the RR501 back in the know good outlet and connected a 2nd RR501 in other parts of the apartment. SAME issue. Switch does not work, unless I get close enough to the RR501 that is plugged into the outlet that is on the same FUSE line.
I hope this clears up my delema.
Thanks again.
