What This Guide Helps With

Troubleshooting incorrect system time, mismatched timestamps, failed patient transfers, or missing patient data caused by settings, identification, connections, or network communication.

Step-by-Step Troubleshooting

1. Ensure Patient Safety First

Do not perform extended troubleshooting while the BeneView monitor is the only device supporting an actively monitored patient.

• Notify the clinical team that timestamps, transferred information, or centrally displayed patient data may be unreliable.
• Confirm that current physiological measurements and alarms remain available at the bedside.
• Transfer the patient to another verified monitor if required monitoring data cannot be reliably viewed, stored, or communicated.
• Do not use questionable timestamps or incomplete transferred data for clinical decision-making.

Expected outcome: Patient monitoring continues without depending on inaccurate time records or failed data communication.

Continue Clinical Engineering troubleshooting only after the affected monitor can be safely evaluated.

2. Confirm the Exact Failure

Determine whether the reported issue involves:

• The displayed date or time being incorrect
• The time resetting after shutdown
• The bedside monitor and central station showing different times
• Trends, alarms, or events having incorrect timestamps
• Patient demographics failing to transfer
• Patient data remaining associated with the previous bed or patient
• Data reaching the central station but not another downstream system
• A patient transfer, admit, or discharge operation failing
• A network, central-station, or communication message appearing

Record the amount of the time difference and whether it remains constant or increases.

Expected outcome: The problem is identified as a local clock issue, network synchronization issue, patient-association issue, or broader data-interface failure.

3. Verify the Correct Patient and Bed Association

Confirm that:

• The correct patient is admitted to the monitor.
• The patient name and identification number match the clinical record.
• The monitor is assigned to the correct bed or location.
• A previous patient has been properly discharged.
• Duplicate or incomplete patient records are not displayed.
• The receiving monitor or central station is using the intended patient record.

Do not merge, discharge, or overwrite patient information without coordinating with clinical staff.

Expected outcome: The monitor displays the correct patient and bed association.

If correcting the patient or bed assignment restores data transfer, confirm the information at the receiving system and stop.

4. Check the Monitor’s Date and Time Display

Compare the monitor’s displayed date and time with an approved hospital time source.

Check for:

• Incorrect date
• Incorrect hour or minute
• Incorrect time format
• A consistent offset suggesting a time-zone or daylight-saving issue
• A clock that resets after power interruption
• A clock that gradually drifts

Do not repeatedly change the local time if the monitor is configured to obtain time from a central monitoring or network system. The BeneView platform supports hospital-network integration, so synchronization behavior may depend on the installed system configuration.

Expected outcome: The displayed time matches the hospital-approved time source or the nature of the time discrepancy is clearly documented.

5. Inspect the Wired Network Connection

For a wired monitor:

• Confirm that the network cable is fully seated at the monitor, docking station, wall jack, or approved network adapter.
• Inspect the cable and connectors for broken locking tabs, bent contacts, contamination, or physical damage.
• Check for network-link or communication indicators when available.
• Verify that the monitor is connected to the correct clinical-network outlet.
• Reseat the cable at both accessible ends.
• Test with a known-good approved network cable.

Do not connect the monitor to an unapproved or general-purpose network.

Expected outcome: The monitor shows an active and stable network connection.

If replacing or reseating the cable restores synchronization or data transfer, verify communication and stop.

6. Check Wireless Communication When Equipped

For monitors using approved wireless communication:

• Confirm that wireless communication is enabled.
• Verify that the expected wireless network or communication symbol is displayed.
• Check whether the problem occurs only in one room or coverage area.
• Move the monitor to a known-good clinical-network location when operationally safe.
• Confirm that the monitor has not been placed in an area with known wireless coverage limitations.
• Compare performance with another compatible monitor in the same location.

Expected outcome: The monitor connects reliably in a known-good coverage area.

If the problem occurs only in one location, document the location and escalate the coverage issue to the appropriate network support team.

7. Compare With Another Networked Monitor

Check a known-good BeneView monitor on the same unit or network segment.

Determine whether:

• Other monitors show the correct time.
• Other monitors can transfer patient information.
• The central station is receiving data from other beds.
• The failure affects only one monitor, one room, one switch area, or the entire unit.

Expected outcome: The problem is isolated to the individual monitor or identified as a broader network or central-system issue.

If multiple monitors are affected, avoid changing individual monitor configurations and escalate the shared communication problem.

8. Check Central-Station Communication

Confirm whether the affected monitor appears at the central monitoring station.

Verify:

• The correct bed label is displayed.
• Current waveforms and numerics are updating.
• Communication-loss or offline messages are present.
• Patient demographics match between the bedside and central station.
• The central station’s displayed time is correct.
• Other beds are communicating normally.

The BeneView T Series is designed to exchange and display information through the hospital network, making central-system availability and correct network association important to data communication.

Expected outcome: Bedside-to-central communication is confirmed or the failure point is narrowed to the monitor, network, or central station.

9. Verify Approved Network Configuration

Using authorized Clinical Engineering or IT documentation, confirm that the monitor has the correct:

• Bed or device name
• Network connection mode
• Internet Protocol address assignment
• Subnet and gateway information, when applicable
• Central-station assignment
• Server or system destination
• Time-synchronization source
• Interface configuration

Compare settings with an approved configuration record or an equivalent working monitor. Do not copy addresses from another active monitor, because duplicate addresses may disrupt communication.

Expected outcome: The monitor’s network identity and destination settings match the approved hospital configuration.

If configuration is incorrect, have authorized personnel restore the approved settings and retest.

10. Evaluate the Patient Transfer Workflow

With clinical staff and interface support as needed:

• Confirm that the patient was properly admitted before attempting transfer.
• Verify that the intended destination bed or monitor is available.
• Check for duplicate admissions or unresolved previous-patient records.
• Confirm that required patient-identification fields are populated.
• Determine whether the transfer fails at the bedside, central station, or electronic medical record interface.
• Avoid creating test patients in the live clinical environment unless hospital policy specifically permits it.

Expected outcome: The patient-transfer process completes and the correct patient information appears at the intended destination.

If the bedside and central station communicate correctly but the downstream patient record does not update, escalate to the clinical-interface or information-technology team.

11. Perform a Controlled Restart

After the monitor has been removed from active patient use:

• Document the current patient and network status.
• Follow the approved shutdown procedure.
• Disconnect unnecessary external accessories that could interfere with startup.
• Restart the monitor.
• Allow the monitor to complete initialization and reconnect to the network.
• Recheck the displayed time, central-station connection, bed assignment, and patient information.

Do not restart a monitor being relied upon for active monitoring.

Expected outcome: Normal network communication and time synchronization return after initialization.

If the issue is resolved, complete a functional verification and stop.

12. Check for Loss of Clock Retention

If the clock is correct while powered but resets after shutdown:

• Connect the monitor to verified AC power.
• Set or synchronize the time through the approved process.
• Shut the monitor down normally.
• Leave it powered off briefly.
• Restart it and compare the displayed time.
• Repeat only as needed to confirm the failure.

A repeated loss of date or time after shutdown may indicate an internal real-time clock, backup-power, or main-board issue.

Expected outcome: The monitor retains the correct date and time through a normal power cycle.

If it does not, remove the device from service for bench evaluation.

13. Complete a Final Functional Verification

Before returning the monitor to service:

• Confirm the date and time against the hospital-approved source.
• Verify that time remains correct after a controlled restart.
• Confirm the correct bed and patient association.
• Verify communication with the central station.
• Confirm that numerics and waveforms update normally.
• Verify that patient data transfers to the intended destination when an approved test method is available.
• Confirm that alarms and event timestamps are recorded correctly.
• Remove any test patient information according to hospital policy.

Expected outcome: Time, patient association, data communication, and timestamped records function correctly.

If the Problem Persists

If the issue remains after patient association, clock settings, cables, network connectivity, central-station communication, approved configuration, and system availability have been checked, common external causes have been ruled out.

The failure may involve:

• Internal clock-retention circuitry
• Network-interface hardware
• Corrupted configuration
• Monitor software
• Central monitoring software
• Network infrastructure
• Patient-data interface or server communication

The device should be:

• Removed from service
• Labeled Out of Service
• Sent for repair or bench evaluation
• Escalated to Mindray, Clinical Engineering network support, or hospital IT as appropriate

Do not perform unapproved software loading, configuration changes, or internal board-level repair. Knowing when to stop and escalate is proper troubleshooting.

Clinical Use Tip

Do not troubleshoot patient-transfer or synchronization failures on an active patient when the integrity of monitoring records could be affected. Establish alternate monitoring and preserve patient identification before restarting, discharging, or reconfiguring the monitor.

Work Order Documentation (CCR Method)

CCR = Complaint, Cause, Resolution

Complaint

What was reported by the clinical staff.

Example:
"Clinical staff reported that the BeneView T Series monitor displayed the wrong time and would not transfer the admitted patient to the central station."

Cause

What was observed during troubleshooting.

Example:
"Found the monitor connected with a damaged network cable, preventing reliable central communication and time synchronization."

Resolution

What action was taken.

Example:
"Replaced the network cable, confirmed the correct patient and bed assignment, verified time synchronization, and successfully tested data communication with the central station."

Helpful Details to Include (If Known)

• Patient removed from the affected monitor before testing
• Reported date and time difference
• Clock compared with approved hospital time source
• Time retained after restart
• Correct patient and bed assignment confirmed
• Previous patient properly discharged
• Network cable inspected or swapped
• Wired or wireless connection status
• Network or communication message displayed
• Central-station connection verified
• Other monitors affected
• Specific rooms or network locations affected
• Patient transfer destination
• Downstream interface or electronic record status
• Controlled restart performed
• Final device status

Final Thought

Time and patient-data failures require careful attention because inaccurate timestamps or incorrect patient association can compromise clinical records. Begin with patient safety, verify identification and external communication paths, isolate the failure logically, and escalate once approved external checks are complete. Thorough CCR documentation helps distinguish monitor failures from network, central-station, and interface problems.

That is successful troubleshooting.
