Sorry my reply is five years after the question but I really hope this reply can help anyone out. I have a gyration GYR3101US Media center remote.
I love this remote/air mouse but after I dropped it about two months back anytime I would try to use the air mouse, it would emit a loud high pitch sound and put the cursor near the time clock unable to move it. Tonight I took it apart. this is what I found. There is one screw behind the batteries, then you have to pry it apart with a flat head. once inside find the gyration sensor
CAREFULLY pry apart the sensor with a little flathead, there is a metal plate on the bottom of the sensor so DO NOT pry from the circuit board up that will break the sensor off. Put the screw driver between the metal plate and the outer casing you should see a little crack. also i cut most of that red tape off with a razor blade before prying.
The red arrow is pointing at the part inside the sensor that had come lose from the drop and was moving about freely inside. I'm guessing it's a weight or magnet. After carefully and gently snapping it back in place, put your mouse back together enough to test it. at first it still had problems but i double clicked the mouse movement button and set it on a flat surface so it could calibrate itself. SUCCESS. I hope this helps my gyration is working fine now. contact me if needed john4628 AT gmail. (There are no fans or bearings in this mouse or any gyration mouse)
