Optional ST analysis and QT/QTc interval monitoring. Extensive data storage plus up to 48 hours of full disclosure Serves as the core parameter module for N-Series monitors Flexible transport solution with optional integrated or modular CO2 IP44 grade particle and water resistant 1.2 m drop test endurance Multiple mounting solutions including transport module rack with bedrail hooks Standard 2.4/5 GHz dual band wireless communication Defibrillator synchronization Battery run time of 8 hours (without integrated CO2)
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.
A parameter drops out or reads wrong
HighSymptoms: ECG, IBP, SpO2, temperature, CO2 or CO intermittently drops or is implausible.
Root cause: Worn patient cable / sensor, or a parameter-module / input-board fault.
NIBP will not measure or is inaccurate
MediumSymptoms: NIBP times out, cuff will not inflate / hold, readings implausible.
Root cause: Internal NIBP pump or valve, a cuff / hose leak, or a pressure-transducer fault.
Module / parameter not recognised
MediumSymptoms: The host does not display a plugged-in module or a built-in parameter.
Root cause: Docking / connector fault or an internal board fault.
Display / touchscreen fault
MediumSymptoms: Blank, dim or distorted display; unresponsive touchscreen.
Root cause: Display, backlight, or controller fault.
Battery / power fault
MediumSymptoms: Short battery run time, will not hold charge, will not power on.
Root cause: Aged battery pack or a power-supply fault.
Network / central-station connectivity fault
LowSymptoms: Monitor not shown at the central station, admit fails, intermittent drop.
Root cause: Wired / Wi-Fi network configuration or a communication board.

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: A parameter drops out or reads wrong (ECG / IBP / SpO2 / temp / CO2 / CO)
- Reseat the patient cable at the module and at the monitor.
- Swap in a known-good cable / sensor for that parameter and re-test.
- Move the module to another host or slot to tell module from host.
- Inspect the module docking connector for bent or recessed pins.
- Verify against a patient simulator; replace the cable, or refer the parameter module / input board if the fault stays with it.
Symptom: NIBP will not measure or is inaccurate
- Leak-test the cuff and hose (occlude and watch for pressure decay).
- Run the monitor's NIBP calibration-verification against a calibrated manometer.
- Confirm correct cuff size and placement and check for a kinked hose.
- Verify against a NIBP simulator at several pressures.
- Refer the monitor for internal pump / valve service if it still fails.
Symptom: Blank / dim / frozen display or unresponsive touchscreen
- Power-cycle the monitor fully (mains removed, battery out where possible).
- Check the display backlight and the display / touchscreen cable.
- Note any boot or self-test error code.
- Re-calibrate the touchscreen if the touch offset is the issue.
- Replace the display / touchscreen assembly or refer the main board.
Symptom: Not shown at the central station / network dropout
- Confirm the wired drop or Wi-Fi settings and that other monitors on that segment are online.
- Check the monitor's network address / unit-bed assignment and re-admit.
- Reseat the network card / cable.
- Restart the monitor's network interface.
- Escalate a whole-unit outage to the central-station server / IT.
