McCormack DNA-1 Problem. Help, please


Hi All,
My clean looking DNA-1 came in yesterday. I got it from a well rated A-goner who said it was functioning perfectly when shipped. It came in very will packed with no sign of damage. When I hooked it up to my Thiel 3.5s to try it out the red protect light on the faceplate came on along with the green power light. I assumed that indicated a problem so I quickly switched it off. I have searched on line for a manual with no success. So, is it a problem? Or should I have not chickened out and let it continue to run. If it is a problem, given that I had not even turned the pre-amp on, could it be something to do with the Thiel equalizer which is on all the time?
Any thoughts (or leads on a manual) would be appreciated since I was really looking forward to hearing how it sounds and don't want to contact the seller untill I'm sure I'm not doing something wrong.
Thanks in advance.

Thanks for all the helpful input, folks. First of all,to Ddd l, I did do a half hour web search for a manual using Bing with no results before posting here. I guess I should have used Google!
Anyway, it turns out that after a phone conversation with the very friendly and helpful Steve McCormack I found that two of the internal fuses were blown, but unfortunately they continued to blow when replaced.
The mystery of why the amp was fine when shipped and DOA when I powered up on arrival has a probable solution. One of the small nuts that mounts the circuit board to the chassis had come loose an was free to go anywhere in the case. Apparently when I powered it up it was shorting something and both blew the fuses and damaged another component in the process, thus causing the new fuses to blow also. It is currently at my local, excellent eledtronics repair shop being diagnosed.
Again, thanks for all the helpful input.
