The company I work at recently moved to a new office building. Dentist office on second floor. I usually leave my Model D the dashboard of my car which is parked about 10 feet from outside wall of the office one floor down. I noticed spikes from about 10 – 12 (normal background) to up to 30 and sometimes 40 during the day. I brought the Model D in and sat it on my desk. I saw the same thing on the display. Catching this happen with the display on I see, for example a 12 (screen refresh) 30 (screen refresh) 18 (screen refresh) back to 12. Quick spikes and and then back down to normal. It happens a few times an hour as a guess.
Has anyone taken their Model D to the dentist? Stood near the x-ray machine with it?
