Red light went on on one of my Ayre MX-R amps


Please advise? My owners manual is in hard place to access. I unplugged the amp and plugged it back in and now it seems to be fine - should i be concerned?

Never read an owners manual where a LED can be so many colors.
Green, blue, red, yellow, violet, orange. Each color is an indication of a different problem. so folks who are color blind should be warned not to buy this electrical device!
I unplugged ny MX-R's last night. Blue to green when turned to stand by. When unplugged I think they switched to Red=>violet=>orange=>green (I think)=>nothing.
I just called Ayre and left a message, now the one amp keeps resetting itself to idle when I have them both off idle, it must be over heating. It has done this at least 4 time in one week now. Something is wrong :(
