system will check the sabotage loop and will
switch to normal system operation where the
loop is in flawless condition. Hence, the device
will switch on automatically after a blackout.
Use the "reset" button to reset the device after

while the button remains pressed. Letting go of
the button will reactivate the interfaces. Hence,
it is possible to reset the device hardware.
