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.
Noisy ECG / lead-off
HighSymptoms: Baseline wander, muscle or AC noise, "lead fail", poor 12-lead quality.
Root cause: Poor skin prep, dried or lifting electrodes, or a worn patient cable / lead set.
Will not acquire or analyse
MediumSymptoms: Acquisition hangs, no interpretation, or a self-test failure.
Root cause: Acquisition-module fault or a software issue.
Printer / recorder fault
MediumSymptoms: No or faint report, paper jam, misregistered grid.
Root cause: Thermal print head, paper handling, or (older units) the stylus.
Battery / power fault
MediumSymptoms: Short battery run time, will not hold charge, will not power on.
Root cause: Aged battery pack.
Connectivity fault
LowSymptoms: ECGs will not transmit to the ECG-management system / EMR.
Root cause: Network / Wi-Fi / modem configuration or the communication module.

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: Noisy ECG
- Re-prep the skin and fit fresh electrodes.
- Secure the lead wires and route away from AC sources.
- Swap in a known-good patient cable / lead set.
- Check the acquisition-module connection.
- Confirm a clean 12-lead on a simulator.
Symptom: Will not print or transmit
- Check the paper and clean the print head.
- Print a test grid / pattern.
- Confirm the network / Wi-Fi / modem settings and send a test ECG.
- Reboot the cart.
- Escalate a persistent print or communication fault.
