Can somebody tell me how to adjust the brightness of the blue circle. The manual says to press Left & Right arrow at the same time, but that doesn't do squat. I've tried pressing left then right, right then left, both at the same time. I tried it with the unit in standby and powered up, and the Cyclops just keeps staring at me. It's starting to freak me out a little. I keep having these weird 2001 dreams. Open the pod door Hal!
