Technical Alarm Conditions When the monitoring system detects an error condition, an error code is displayed on the LCD. Table 11-3 provides a complete list of error codes and problem identification. If an error code occurs, turn the monitoring system off and then on again. Note: If the alarm message still appears, record the error code, take the monitoring system out of service, and contact Covidien Technical Services for advice on remedial action.
