Originally posted by **alfmck** March 31, 2024 After flashed radpro I noticed that when my GC-01 is in measurement state, time by time it enters in MODE state. I checked the signals on buttons wires with oscilloscope and saw that the short pulses to ground induces from high voltage generator. The biggest of them were on MODE button wire. It looks that the button state scanning algorithm sometimes detects these pulses as the MODE button was pressed. My GC-01 has a H614 tube soldered nearby this button. Maybe there was defect in pin9 of CH32F103R8T6 that after trying physically filter that pulse, pin9 on MC became faulty. So, I'm going to reprogram radpro, making button UP to fulfill MODE button function. Thank Gissio that You supplied distributives.

Apparently solved in 2.0rc3.
