Anti-Shock System Conductivity Fault
The FOREO BEAR 2 utilizes an integrated Anti-Shock System that samples skin conductivity across the metallic microcurrent spheres at 200 Hz. Five rapid white LED flashes indicate an out-of-range impedance measurement, open circuit, or excessive surface capacitance, triggering a protection cut-off to prevent galvanic shock.
Rapid Blinking LED Impedance Fault
The FOREO BEAR 2 Anti-Shock System initiates an automatic protection shutdown when its constant-current generator encounters out-of-range skin resistance (typically >500kΩ open-circuit or <1kΩ direct dead-short across dual metallic sphere electrodes), triggering a rapid white LED strobe and immediate power cut.
Microcurrent Impedance Timeout Protection
The FOREO BEAR 2 Anti-Shock System registers an open-circuit or excessive contact impedance across its dual microcurrent spheres exceeding safety thresholds (>150 kΩ) under load. After attempting output current stabilization, the microcontroller's ADC triggers a firmware impedance timeout and safety crowbar protection, signaling a triple white LED blink.
Anti-Shock Impedance Circuit Fault
The Foreo BEAR 2 Anti-Shock System 2.0 tripped due to an out-of-tolerance skin contact impedance measurement (<100 Ω short circuit or >500 kΩ open circuit), triggering a rapid white LED flash and disabling microcurrent output.
