What This Guide Helps With
Troubleshoot unresponsive optional patient controls, foot controls, or caregiver lockouts caused by power, damaged accessories, connection problems, or disabled functions.
Step-by-Step Troubleshooting
1. Protect Patient Safety and Positioning Access
Determine whether the unresponsive control prevents necessary patient positioning.
Provide another verified means of positioning or transfer the patient to a functional bed when needed.
Do not troubleshoot an unreliable control while a patient depends on it.
Secure the unoccupied bed before testing.
Expected outcome: Required patient positioning remains available through safe equipment.
2. Identify the Affected Control
Confirm whether the problem involves:
- Patient pendant
- Foot control
- Caregiver control panel
- Function lockout
- Multiple control locations
Verify which optional accessories are actually installed on the bed.
Expected outcome: The affected control and installed configuration are identified.
3. Verify AC Power
Inspect the power cord and connect the bed to a verified appropriate outlet.
Check whether normal powered functions respond from another authorized control location.
Observe available power indicators.
Expected outcome: The bed has stable power and basic positioning capability.
4. Inspect Control Buttons and Housings
Check the affected control for visible damage, contamination, sticking buttons, or cracked housings.
Inspect for evidence of liquid intrusion.
Do not continue operating visibly damaged electrical controls.
Expected outcome: The control is physically intact and safe to test.
5. Inspect External Cables and Connectors
For detachable accessories, inspect accessible cables and connectors.
Look for pinched wiring, broken strain relief, loose plugs, or bent contacts.
Reconnect approved detachable accessories when safe.
Do not open sealed controls or disturb internal wiring.
Expected outcome: External control connections are secure and undamaged.
6. Verify Caregiver Lockout Settings
Inspect the authorized caregiver lockout controls.
Determine whether the affected function is intentionally disabled.
With clinical approval, restore the required function using the normal control interface.
Confirm that lockout indicators reflect the selected state.
Expected outcome: Enabled functions respond and disabled functions remain appropriately restricted.
7. Compare Alternate Controls
Test the same movement using another installed control location.
If the function works from the caregiver panel but not the pendant, the issue may be localized to the pendant or its connection.
If the function fails everywhere, consider shared control, power, or movement-related causes.
Expected outcome: The failure is isolated to an accessory or shared bed function.
8. Substitute an Approved Known-Good Accessory
If the affected pendant or foot control is detachable and approved for substitution, connect a compatible known-good accessory.
Verify operation without altering internal configuration.
Do not interchange incompatible accessories.
Expected outcome: Accessory substitution identifies whether the external control caused the failure.
9. Perform Final Control and Lockout Verification
Test each affected control through a safe movement range.
Verify correct direction, stopping, and normal response.
Enable and disable applicable lockouts and confirm that the intended functions respond correctly.
If all required checks pass, troubleshooting can stop.
Expected outcome: Controls and lockouts operate reliably according to the installed configuration.
If the Problem Persists
External power, control condition, connections, lockouts, and approved accessory substitutions have been checked.
Remaining causes may include internal control circuitry, wiring, input interfaces, or actuator control systems.
Remove the bed from service, label it Out of Service, and arrange qualified repair or bench evaluation using Stryker documentation and approved test equipment.
Replace or repair components only through authorized procedures.
Verify all affected controls and lockouts before return to service.
Knowing when to stop external troubleshooting is proper troubleshooting.
Clinical Use Tip
Confirm that caregiver lockouts prevent unintended patient-operated movement while allowing required staff positioning functions.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Nursing reported that the Secure II patient pendant would not raise or lower the head section."
Cause
What was observed during troubleshooting.
Example:
"Clinical Engineering found that the patient Fowler control was disabled by the caregiver lockout."
Resolution
What action was taken.
Example:
"Restored the authorized control setting with nursing approval and verified normal pendant movement and lockout operation."
Helpful Details to Include (If Known)
- Installed control accessories
- Affected control location
- Specific function unavailable
- AC power status
- Button and housing condition
- Cable and connector condition
- Lockout indicators
- Alternate control results
- Known-good accessory results
- Final control and lockout verification
Final Thought
Unresponsive bed controls should be evaluated through power, accessories, connections, and lockout settings before internal faults are suspected. Maintain patient positioning safety, verify every affected control, escalate unresolved failures, and document the corrective action clearly.
That is successful troubleshooting.
