What This Guide Helps With

Troubleshooting failure to start, repeated restarting, or freezing caused by power, battery, accessories, external devices, software state, or internal faults.

Step-by-Step Troubleshooting

1. Ensure Patient Safety and Transfer Monitoring

Do not troubleshoot a Philips Avalon FM30 that will not start, repeatedly reboots, or freezes while a patient depends on it.

Notify clinical staff and transfer fetal and maternal monitoring to another verified device. Confirm all required channels, alarms, and central-monitoring functions are active on the replacement monitor.

Expected outcome: Patient care continues without reliance on the unstable monitor.

2. Confirm the Exact Startup or Freeze Behavior

Determine whether the monitor:

• Shows no signs of power.
• Starts and stops at the same screen.
• Reboots repeatedly.
• Reaches the operating display and then freezes.
• Freezes after a specific accessory is connected.
• Operates on AC but not battery.
• Operates on battery but not AC.
• Displays an error or status message.
• Recently experienced a power interruption, fluid exposure, impact, software update, or configuration change.

Record the last normal operating state and any displayed message.

Expected outcome: The failure is categorized as no power, interrupted boot, repeated restart, post-startup freeze, or accessory-triggered failure.

3. Inspect for Damage or Hazardous Conditions

Check the monitor, power inlet, battery area, display, and connected accessories for:

• Fluid intrusion.
• Cracks or impact damage.
• Burn marks.
• Unusual odor.
• Excessive heat.
• Swollen battery.
• Loose parts.
• Damaged connectors.
• Contamination.

Do not energize a monitor with evidence of fluid intrusion, burning, battery swelling, or severe physical damage.

Expected outcome: No immediate electrical or battery hazard is present. If a hazard is found, remove the unit from service and escalate without further power testing.

4. Verify the AC Outlet

Test the outlet using an approved method. Confirm the receptacle is energized and not controlled by a wall switch.

Expected outcome: A reliable AC source is available. A failed outlet is referred to Facilities and the monitor is tested at a verified source.

5. Inspect the Power Cord

Check the power cord for cuts, fraying, crushed insulation, damaged plug blades, heat damage, or loose strain reliefs.

Connect the cord fully to the monitor and outlet. Substitute a known-good approved cord when needed.

Expected outcome: The monitor receives stable AC power. If a replacement cord resolves startup, complete extended verification and stop troubleshooting.

6. Compare AC and Battery Operation

Attempt startup on verified AC power and, when safe, with the installed battery according to approved procedure.

Note whether the failure occurs:

• Only on AC.
• Only on battery.
• During transfer between power sources.
• On both power sources.

Expected outcome: The power-source comparison narrows the problem to external AC supply, battery, charging system, or a broader monitor failure.

7. Disconnect Nonessential External Accessories

Remove nonessential transducers, patient cables, USB devices, scanners, network adapters, external interfaces, and other accessories.

Leave only the connections necessary for a basic startup test. Disconnect accessories only after the monitor is no longer assigned to a patient.

Expected outcome: The monitor starts normally with accessories removed. Reconnect approved accessories one at a time to identify any item that triggers the failure.

8. Inspect External Ports and Accessories

Check each disconnected accessory and port for:

• Bent contacts.
• Fluid contamination.
• Damaged connector shells.
• Shorted or crushed cables.
• Foreign material.
• Loose retention.
• Unsupported devices.

Do not reconnect a damaged accessory.

Expected outcome: All external accessories and ports are free of obvious faults. Any suspect accessory is removed from service and tested separately.

9. Perform an Approved Power Cycle

Use the normal shutdown and startup process when possible.

For a frozen monitor that will not respond, follow the approved Philips procedure for removing power. Do not repeatedly interrupt power during boot, and do not perform undocumented reset combinations.

Expected outcome: The monitor completes startup and remains responsive. A single recovered freeze still requires observation and full functional verification.

10. Observe Startup Without Network Connection

If authorized by local policy, disconnect the external network or central interface and restart the monitor.

Maintain cybersecurity and patient-data procedures. Do not alter network configuration.

Expected outcome: Normal startup without the external connection may indicate an interface, network, or external-system interaction requiring escalation.

11. Reconnect Accessories Individually

After a successful basic startup, reconnect each approved accessory one at a time while observing monitor stability.

Allow sufficient time between connections to identify a delayed freeze or reboot.

Expected outcome: The monitor remains stable, or one accessory or interface reproducibly triggers the failure.

12. Review Recent Changes and Work History

Check for:

• Recent battery replacement.
• Software or configuration changes.
• Network or interface changes.
• Prior freeze or reboot complaints.
• Impact or fluid incidents.
• Newly introduced accessories.
• Previous unresolved repair.

Do not reverse software or configuration changes without approved documentation and change control.

Expected outcome: A relevant recent change is identified for controlled evaluation by the appropriate support group.

13. Perform Extended Functional Observation

If the monitor starts normally:

• Allow it to remain powered through an extended observation.
• Operate representative monitoring channels with approved simulators.
• Navigate normal user screens.
• Verify alarms.
• Check AC-to-battery transfer.

Connect required interfaces.

Observe for freezing, restarting, delayed response, or abnormal heat.

Expected outcome: The monitor remains stable under representative operation.

14. Perform Final Functional Verification

Before return to service:

• Confirm repeated normal startup and shutdown.
• Verify display and controls.
• Test required fetal and maternal channels.
• Verify alarm generation and annunciation.
• Confirm accessory recognition.
• Verify network or central transfer when required.
• Confirm AC and battery operation.
• Complete electrical safety and applicable performance testing.
• Confirm no recurrence during observation.

Expected outcome: The monitor is stable and all required functions pass. Troubleshooting can stop.

15. Stop and Escalate When Instability Persists

Remove the Philips Avalon FM30 from service when:

• It remains in a boot loop.
• It freezes again during observation.
• Startup fails on both AC and battery.
• A known-good power cord and verified outlet do not correct the issue.
• Multiple approved accessories trigger instability.
• The display remains blank or distorted.
• The device becomes unusually hot.
• There is evidence of fluid intrusion.
• Software recovery or internal repair is required.

Expected outcome: An unstable monitor is not returned to patient care.

If the Problem Persists

Common external causes such as the outlet, power cord, battery condition, damaged accessories, contaminated ports, and external interface problems have been ruled out. The remaining cause may involve the internal power supply, processor, memory, storage, display electronics, software, configuration, or internal communication.

Remove the device from service, label it Out of Service, and send it for bench evaluation using current Philips service documentation and approved test equipment. Software recovery, configuration restoration, internal repair, and component replacement should be completed only by qualified personnel.

Return the monitor to service only after repeated startup, extended stability, all required measurement channels, alarms, controls, communications, battery operation, and applicable safety tests pass. Knowing when to stop external troubleshooting is proper troubleshooting.

Clinical Use Tip

A monitor that recovers after one restart should still complete extended functional testing before returning to fetal monitoring service.

Work Order Documentation (CCR Method)

CCR = Complaint, Cause, Resolution

Complaint

What was reported by the clinical staff.

Example:
"Clinical staff reported that the Philips Avalon FM30 repeatedly restarted before reaching the normal monitoring display."

Cause

What was observed during troubleshooting.

Example:
"Clinical Engineering found that a damaged USB accessory caused the monitor to restart during startup; the monitor booted normally with the accessory disconnected."

Resolution

What action was taken.

Example:
"The accessory was removed from service, and repeated startup, extended operation, monitoring channels, alarms, controls, battery transfer, and central communication were verified."

Helpful Details to Include (If Known)

• Exact startup or freeze behavior.
• Last screen or displayed message.
• AC and battery operation.
• Outlet and power-cord results.
• Physical damage, heat, odor, or fluid exposure.
• Accessories connected at failure.
• Behavior with accessories disconnected.
• Network-connected versus disconnected behavior.
• Recent software or configuration changes.
• Duration of extended observation.
• Final functional and safety test results.
• Final equipment disposition.

Final Thought

Transfer monitoring first, verify power and external accessories before assuming internal failure, observe the monitor long enough to detect recurrence, escalate instability appropriately, and document the complete verification.

That is successful troubleshooting.
