Use a small flat bladed screwdriver with the blade wrapped with a little electricians tape to prevent scarring the wood bezel. Start at the top front of the bezel working the blade between the bezel and the undermount. There is a tab that you need to find and push in with the blade. Then you can lift the bezel up from the front and the whole unit can then lift out. There are a couple of smaller tabs along the right side of the bezel and maybe one at the bottom but once you get the large one up under the top depressed, the rest seem to pop out. It's a little dicey doing it the first time but be patient and work carefully and after you do it once it is pretty easy because you know where to locate that first tab. Good luck.
