Ok, first let me say thanks for the help. The 1423 code worked perfectly on the RCRP05B remote so I'm happy.

I decided to try the same code on the Atlas, but it only partially worked. I was able to get to the input menu and highlight the different options, but pressing the enter button didn't work. When I tried using the other codes, I couldn't even bring up the input menu.

I really want to get my Atlas working and return the RCRP05B to the store. Code 1423 felt like a step closer; is there anything else to try with the Atlas? If not, I'm happy with the RCRP05B, it only cost like $16.
