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.

Documents & Manuals
Safety & Recalls
Synced live from the FDA openFDA API.
- RECALL
When the Worstation of the BeneVision DMS has a specific hardware configuration, the computer may experience audio playback failure or screen freezing.
- RECALL
Potential for activation of an abnormal alarm pause.
- RECALL
Telepack may not power on when using the 3AA battery cradle.
- RECALL
BeneVision DMS may intermittently freeze and require a manual reboot after which normal operation resumes. If a freeze occur, patients monitored on a telemetry transmitter will no longer communicate data to the BeneVision DMS
- RECALL
The firm has identified performance anomalies with the device caused when more than 64 TD60 telemetry transmitters have been connected to a central station. The anomaly causes some ECG waveforms to appear as a flat line at the centralized viewing station and will manifest if more than 64 TD60 transmitters have been connected to a given central station server. Each central station supports only 32 transmitters at a time. For the issue to manifest, the BeneVision DMS needs to be configured to use flexible device assignment, have more than 64 TD60 transmitters, and the workflow must allow 64 TD60s to move around between multiple central stations in the same care area.
- RECALL
A damaged circuit board in the battery charger can cause the battery to overcharge and the battery case to swell and separate.
