Logging data after a power loss
If power is unexpectedly lost while the receiver is logging data, once power is restored,
the receiver tries to return to the state it was in immediately before the power loss. The
receiver does not reset itself to default settings.
If the receiver was logging data when power was lost, data logging is resumed when
power is provided.
