Help: Classe CP47.5 owner w/ Logitech Harmony Remote

Hi everyone,

I recently bought a used Classé CP47.5 preamp. Everything works beautifully. The only thing is that the unit doesn't come with original remote control. I thought no problem since I use Harmony anyways. Well, turns out the power toggle code from my Harmony doesn't work, all other commands are fine. So here is the conundrum. I don't know if the Harmony code is wrong for the CP47.5 or if it's only my unit that has problem responding to the power toggle signal. To start the diagnosis, I am asking those of you who use Harmony with your CP47.5, does the power toggle command works for you?

Thanks in advance for your help.
