Figured it out. There are two screws on the bottom. Then you push on the front above the power light. This area is glossy, not matte. This releases a plastic hook inside. Next you continue to push in on the front and begin to push up (same place, Just above the power light. The whole top pops off. Don't worry about the cable powering the blue LED display, it is long enough to take the top off and flip it over without disconnecting. Figuring out how to get the exterior buttons (plastic) to line up with the interior button (metal box with white tiny plastic industrial looking button) took a little more finesse. I removed the plastic button holster from two tiny plastic ****gs with the blade of a small flat head screwdriver. Careful! If you break these you will be using super glue to get your buttons back on. I re-bent the plastic spring (Long flat C shaped pieces above and below each button) that gives the buttons that familiar feel, then pushed the button holster back onto the plastic ****gs. I reassembled the whole unit and it works like a charm. I should note that I attempted to adjust the buttons without removing the button holster first, but the plastic button springs were bent, and they can't be bent back flat without removing them.
