The GMC-300E has been check out and many bugs fixed, so lets look at other conditions.
1. Did you see the GMC-300E hit 2000 on the display?
2. Was the unit at the window during this event of 2000?
3. I have a Colman mantle lantern, it is radioactive. Do you have anything like that, or dishes, watches?
