90-day warranty 110/ 220 volt compatible 60/ 50 Hz Excellent condition.
Key tips
- ·A no-signal/flatline alarm gets checked on the patient first, not the monitor - rule out a real clinical event before troubleshooting.
- ·Recalibrate NIBP against a reference manometer, not just a self-test pass.
- ·Reused patient cables (SpO2, ECG leads) are a common source of intermittent-fault complaints - swap the cable before the module.
Typical Failure Modes
Compiled for this model from its own documentation and established engineering knowledge for this equipment class - not from a verified service record. Confirm against the manufacturer's service manual.
No SpO2 / pulse reading or poor signal
HighSymptoms: No saturation / pulse value, "pulse search", low signal quality, implausible values.
Root cause: Worn or wrong SpO2 sensor, a damaged cable, poor site / perfusion, or motion.
Sensor / cable connector fault
MediumSymptoms: Reading drops when the cable is moved, sensor not recognised.
Root cause: Broken conductors in the sensor / extension cable, or a worn connector.
Inaccurate SpO2 vs a co-oximeter
MediumSymptoms: SpO2 consistently biased vs an arterial reference.
Root cause: Sensor degradation, or a monitor calibration / module fault.
Alarm / audio fault
MediumSymptoms: No or quiet audible alarm.
Root cause: Speaker or audio-board fault - a safety-critical failure.
Battery / power fault
MediumSymptoms: Short battery run time, will not power on.
Root cause: Aged battery.

PM Checklist
Preventive-maintenance tasks typical of this equipment class. Perform to the manufacturer's procedure and your facility's policy - this is general reference, not a schedule for this specific unit.
- ·Routine cable and lead-wire inspection for fraying/wear
- ·Battery conditioning cycle
- ·NIBP calibration check against a reference manometer
- ·ECG / SpO2 accuracy verification against a patient simulator
- ·Annual electrical safety test
Troubleshooting Approach
A starting sequence for this model, compiled from its documentation and engineering knowledge for this equipment class. Follow the manufacturer's service documentation for the actual procedure.
Symptom: No SpO2 or poor signal
- Fit a fresh, correct-size sensor on a well-perfused, still site.
- Swap the extension cable.
- Confirm the signal-quality / pleth indicator improves.
- Test the monitor with an SpO2 simulator.
- Replace the sensor / cable, or refer the monitor if the simulator also fails.
Symptom: Accuracy or alarm concern
- Compare SpO2 to a co-oximeter blood gas where clinically indicated.
- Try a known-good sensor.
- Verify against an SpO2 simulator at several saturations.
- Test the audible alarm at the set volume.
- Refer for module / audio service if it fails the simulator or alarm test.

- RECALL
Unintended shut-down: The anesthesia machine may start shutting down without human intervention due to a faulty On/Standby Switch. Prior to shutdown, the system will issue an alarm and play a message that shutdown will occur in 8 seconds. The failure only affects the electrical portion of the switch. If the clinician does not intervene, the patient could experience hypoventilation leading to h

Issue 1 -Possible failure of CIC Pro audible alarms: Requests for telemetry defaults from Mobile Care Server could cause excessive CIC Pro memory consumption. This excessive memory consumption may lead to potential loss of audio at the CIC or a system reset or reboot.

There is a correction associated with Engstrom Carestation with an integrated Aerogen Professional Nebulizer System. There is an issue relating to the removal of the nebulizer cable from nebulizer connection port, which, when done while the nebulizer is active, may result in the discontinuance of mechanical ventilation. This issue affects all of the Engstrm Carestations shipped between 12/4/2006
- RECALL
Alarm sound-It is possible that the audible alarms from the speaker from the Datex-Ohmeda S/5 Anesthesia Delivery Unit (ADU) machine may dampen or disappear as a result of normal handling of the anesthesia machine. Visual alarms on the ADU are unaffected by this condition. The dampening or absence of audible alarms on the ADU may result in a delay in treatment.
