MONITORING DETECTS AN ERROR
The two LEDs blink quickly (2 or 4 quick flashes followed by a 1 sec break, depending on the detected error):
1. Type 1 failure: Code execution and internal micro-controller state consistency. If a problem is detected, the
system is reset.
2. Type 2 failure: Micro-controller oscillator monitoring. If a problem is detected, the system enters in "fault
mode". The LEDs show a code by blinking twice followed by a 1 second pause.
3. Type 3 failure: Microwave oscillator and receiver chain. If a problem is detected, the LEDs show a code by
blinking four times followed by a 1 second pause.
The reset takes1,500 milliseconds.
