ultima 8 electrical question

I have an ultima 8 with the newer powered wedge and the PEC it runs off of the 9v battery. I have a universal 110 adapter and I don't know how to set it for this scope. Does any one know the voltege and polarity for this set up. I will try Celestron but I know they are moving. I don't want to burn up this set up by doing it wrong!
Thanks for your time

Celestron callled me at home on this question. Yes it took about 4 days but they were moving. And the info I needed was 100% on! (Thanks John at Celestron) The number I used was 1-800-421-9649 My hat's off to Celestron.
Ps I LOVE THE ULTIMA 8
