I am moving and would like to take my Hampton Bay fan with me to my new house. The problem is that I can't see how to remove it from the ceiling. I am embarrassed to say I installed it myself about a year ago and I can't remember how I finished it off.. there are no exposed screws at the top of the hanger cover or whatever you call it.

There is a decorative ring covering the screws on the ceiling piece. It twists off.
