I would like to open with the statement your problem description could be somewhat more elaborate.
Most of the people answering questions here have super fun jobs they don't like to be away from for too long, so any work you offload on us (such as finding out the actual brand, what it should look like, etc) will makes an answer less likely.
I'm still not 100% sure I have the thing right, but I'm guessing there's not that many "e200c" + "rf" devices out there.
That said, just typing "e200c rf" into google popped up this link:
Does that answer your question? I can't watch it right now, as I only have a few minutes before my simulation ends and I have to do real work again.
