I accidentally used the wrong ac adapter on my UR 44. Is there an internal fuse?

I accidentally used the wrong ac adapter on my UR 44. It powered up for a second and went dead. I found the proper adapter but the unit is completely dead. Is there an internal fuse that I might change? Or is it toast?

I do not think there is. Sorry.

I didn’t think so - Thanks for taking the time to post Steve. Tim
