What This Guide Helps With
Troubleshooting missing, dim, incorrect, or intermittent bed lighting caused by power, settings, obstruction, contamination, connections, or a service-level lighting fault.
Step-by-Step Troubleshooting
1. Protect the Patient and Maintain Safe Visibility
Do not rely on a failed night light, underbed light, or status indicator when it is needed for patient observation, fall prevention, brake confirmation, alarm awareness, or safe room navigation.
Provide alternate room lighting or another verified method to confirm the affected status.
Expected outcome: Clinical staff can safely observe the patient, bed, floor area, and required status information.
If the failed indicator prevents staff from confirming a critical bed condition, remove the bed from service or restrict use until another reliable method is established.
2. Confirm the Exact Lighting Failure
Determine whether the issue involves:
- Night light
- Underbed light
- Brake indicator
- Bed-exit or alarm indicator
- Side-rail status light
- Power indicator
- One light or several lights
- Incorrect color or state
- Dim, flickering, intermittent, or completely dark operation
Confirm whether the underlying bed function itself works correctly.
Expected outcome: The failure is separated into a lighting problem, a status-detection problem, or both.
If the indicator accurately changes after normal operation is restored, troubleshooting can stop after final verification.
3. Verify AC Power and Bed Operation
Confirm that the bed is connected to a functioning approved receptacle and has completed normal startup. Inspect the power cord and verify unrelated powered functions.
Observe whether the light behaves differently on AC power and battery power.
Expected outcome: The bed has stable power and the lighting failure is not caused by loss of primary power.
If restoring power returns normal lighting, verify all related indicators and troubleshooting can stop.
4. Check Normal Lighting Controls and Settings
Inspect the standard caregiver controls for night-light, underbed-light, dimming, or lighting selections. Confirm that the light has not been intentionally disabled.
Do not enter restricted service menus or alter unrelated configuration.
Expected outcome: The affected light is enabled through normal controls.
If enabling the light restores steady operation, verify repeated on/off control and troubleshooting can stop.
5. Confirm the Status Being Indicated
For a status indicator, place the unoccupied bed in a safe condition and operate the related function, such as setting and releasing the brake or changing a side-rail position.
Observe whether:
- The mechanical function changes
- The local control display changes
- The external indicator changes
- The remote status system changes, when applicable
Expected outcome: The problem is isolated to the lamp or indicator, status sensing, or communication path.
Do not assume the lamp is defective if the underlying status is also incorrect.
6. Inspect for Obstruction, Contamination, or Physical Damage
Inspect the light lens and surrounding area for:
- Linens or equipment covering the light
- Dirt or residue
- Tape or labels
- Cracked lens
- Loose housing
- Impact damage
- Liquid intrusion
- Discoloration or heat damage
Clean only according to approved facility and manufacturer-compatible methods.
Expected outcome: The light output is unobstructed and the housing is secure and undamaged.
If removing an obstruction or approved cleaning restores normal visibility, verify operation and troubleshooting can stop.
7. Observe for Intermittent Operation During Bed Movement
With the bed unoccupied, safely operate height or articulation controls while observing the light.
Do not place hands near moving components. Note whether the light flickers when the frame moves or when an external cable is gently repositioned.
Expected outcome: The light remains stable during normal bed movement.
Flickering associated with frame movement suggests a harness or connection problem and requires service-level evaluation.
8. Inspect Accessible External Connections
Disconnect AC power and follow facility procedures before inspecting accessible lighting modules, connectors, cable routing, and mounting points.
Look for a loose connector, pinched harness, abrasion, liquid contamination, or impact damage. Do not open sealed modules or controller enclosures.
Expected outcome: Accessible lighting connections are secure and the wiring is protected from bed movement.
If securing an intended service-access connector restores the light, complete repeated functional verification before return to service.
9. Compare With Other Indicators
Compare the affected light with another equivalent indicator or a known-good ProCuity bed.
Confirm whether brightness, color, timing, and response are consistent under the same condition.
Expected outcome: Normal behavior is confirmed without relying on memory or assumption.
If the light is functioning as designed, explain the verified operation to staff and document that no fault was reproduced.
10. Complete Final Functional Verification
Test the light through all applicable normal states. Verify:
- On and off control
- Correct response to the associated bed status
- Stable brightness
- No flicker
- No abnormal heat
- Visibility from the intended location
- Correct remote status when applicable
Expected outcome: The light or indicator operates consistently and accurately represents the associated bed condition.
Troubleshooting can stop when the lighting and underlying status function both verify correctly.
If the Problem Persists
Common external causes such as bed power, normal settings, obstruction, contamination, physical damage, and accessible connections have been ruled out.
The remaining cause may involve an LED or lighting assembly, internal harness, status sensor, control board, software configuration, or communication system.
The bed should be:
- Removed from service if the failed indicator affects safe clinical operation
- Labeled Out of Service or restricted from the affected use
- Sent for repair or bench evaluation
- Evaluated using appropriate Stryker documentation and approved test equipment
- Repaired or configured only by qualified personnel
Do not bypass an indicator or assume the underlying bed status is safe without independent verification. Complete full functional testing after repair.
Knowing when to stop external troubleshooting is proper troubleshooting.
Clinical Use Tip
Provide alternate lighting or status confirmation so staff do not depend on a missing or incorrect visual indicator.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Nursing reported that the underbed light remained off when selected from the caregiver control."
Cause
What was observed during troubleshooting.
Example:
"Clinical Engineering found the underbed-light lens completely covered by a secured linen-management pouch."
Resolution
What action was taken.
Example:
"Repositioned the pouch, verified unobstructed light output, and confirmed reliable on-and-off control from the caregiver panel."
Helpful Details to Include (If Known)
- Exact light or indicator affected
- Dark, dim, flickering, or incorrect behavior
- AC or battery operation
- Related bed status
- Normal control setting
- Lens and housing condition
- Obstruction or contamination found
- Behavior during bed movement
- Accessible connector condition
- Comparison with a known-good bed
- Final functional result
- Final device status
Final Thought
Maintain safe visibility, verify the underlying bed status as well as the light, rule out simple obstruction and settings, escalate internal faults appropriately, and document the final verified condition.
That is successful troubleshooting.
