A malfunction is detected. There are
two possible causes of these
failures. First, the power provided to
the board is out of specification. In
this case, the failure may be cleared
once the underlying cause is
removed. Second, the board has an
actual hardware failure and recovery
is not possible. It is recommended
that the SpO2 module be replaced,
and if problem is still present replace
the monitor's main board.
