Correctable error conditions
When an error code other than a correctable error appears, turn the monitor-
ing system off and back on again. If the error code reappears, record it and
notify service personnel. When this occurs, the monitoring system will stop
monitoring the patient until the caregiver takes corrective action and clears the
error condition.
