What This Guide Helps With
Troubleshooting failed lighting or status indication caused by power, settings, ambient conditions, controls, connections, damage, or isolated light failure.
Step-by-Step Troubleshooting
1. Ensure Patient Safety and Provide Alternate Visibility
A failed night light or status indicator can increase fall risk or cause staff to misinterpret bed condition.
Notify clinical staff. Provide alternate room lighting or direct verification of brake, rail, alarm, or other safety status as appropriate. Do not rely on an indicator that has not been verified.
Expected outcome: Staff and the patient have adequate visibility and do not depend on an uncertain status display.
2. Confirm the Exact Failed Function
Determine whether the issue affects:
The night light.
The underbed light.
One or several status indicators.
One side of the bed.
A light that is always off, always on, dim, flickering, or intermittent.
Lighting only on AC power or only on battery.
Expected outcome: The specific lighting or indicator function and failure pattern are clearly identified.
3. Verify Bed Power
Confirm that the bed is connected to verified AC power and shows normal operating status.
Check battery condition if the failure occurs while unplugged. Determine whether other displays, controls, or powered functions are also affected.
Expected outcome: Stable bed power is confirmed. A broader power problem is corrected before treating the light as an isolated failure.
4. Verify User Controls and Settings
Check the appropriate user-accessible light control or display setting.
Confirm that the light is not intentionally turned off, dimmed, or affected by an active mode or lockout. Do not enter unauthorized service menus.
Expected outcome: The intended lighting function is enabled. If correcting the setting restores normal operation, test it repeatedly and stop troubleshooting.
5. Consider Ambient-Light Conditions
Some lighting behavior may appear different in a brightly lit room.
Reduce room lighting only when safe and operationally appropriate to confirm whether the night or underbed light is actually activating.
Expected outcome: The function is assessed under conditions where its output can be seen clearly.
6. Inspect the Light and Lens
Inspect the affected lens, indicator window, or light assembly for:
Dirt or residue obscuring output.
Cracks, impact damage, or missing covers.
Fluid intrusion.
Loose external housing.
Tape, labels, linens, or accessories blocking the light.
Clean only with approved methods and do not direct liquid into the assembly.
Expected outcome: The light path is clean and unobstructed. If cleaning or removing an obstruction restores visibility, verify operation and stop.
7. Verify the Associated Bed Condition
For a status indicator, operate the related function safely and confirm whether the indicator changes.
Examples may include brake, side-rail, bed-position, or alarm status. Perform the test without a patient when movement or safety systems are involved.
Expected outcome:
If the bed function changes but the indicator does not, the issue is likely isolated to indication or communication.
If neither the function nor indicator changes, troubleshoot the associated bed function first.
8. Inspect Accessible External Connections
With the bed removed from patient use, inspect only externally accessible light or control connections allowed by approved procedures.
Look for loose connectors, pinched cables, damage near moving frame sections, or contamination.
Expected outcome: Accessible wiring and connectors are secure and undamaged. If reseating restores operation, reposition the bed and retest for intermittency.
9. Compare Similar Indicators or Controls
Compare the affected light with the corresponding indicator on the opposite side or another verified InTouch bed when available.
Use the comparison to confirm expected brightness and behavior without assuming all lights operate identically.
Expected outcome: The abnormal function is confirmed and isolated.
10. Perform Final Functional Verification
After correction, cycle the applicable control or bed condition several times.
Confirm that the light activates, extinguishes, or changes state consistently without flickering. Verify that the associated bed function itself remains normal.
Expected outcome: Lighting or indication is reliable and correctly represents bed status. Troubleshooting can stop.
11. Escalate an Unresolved Lighting Failure
Remove the bed from service when the failed indicator communicates a safety-critical condition and no alternate approved verification method is available.
For noncritical lighting, follow facility policy for repair priority and temporary use. Label the failed function clearly so staff are not misled.
Expected outcome: The bed is not used in a manner that depends on an unreliable safety indicator.
If the Problem Persists
Power, controls, settings, ambient conditions, cleanliness, associated bed functions, and accessible connections have been evaluated. The remaining cause may involve the lamp or LED assembly, indicator driver, internal wiring, control board, sensor input, or approved configuration.
Remove the bed from service when required, label it Out of Service, and evaluate it using appropriate Stryker documentation and approved test equipment. Repairs should be performed only by qualified personnel. Verify the light, associated bed condition, and any related alarm or display before return to service.
Knowing when to stop external troubleshooting and escalate is proper troubleshooting.
Clinical Use Tip
Directly verify the actual brake, rail, alarm, or bed condition whenever its corresponding status indicator is questionable.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Nursing reported that the InTouch underbed light did not illuminate when activated."
Cause
What was observed during troubleshooting.
Example:
"Clinical Engineering found the light lens covered by an adhesive equipment label that blocked most of the output."
Resolution
What action was taken.
Example:
"Clinical Engineering removed the obstruction, cleaned the lens with an approved method, and verified consistent underbed-light operation."
Helpful Details to Include (If Known)
- Light or indicator affected.
- Off, dim, flickering, intermittent, or always-on behavior.
- AC and battery status.
- Control or setting observed.
- Ambient-light conditions.
- Lens and housing condition.
- Associated bed function tested.
- Opposite-side or known-good comparison.
- External connection condition.
- Final lighting and status-verification result.
Final Thought
Maintain safe visibility, confirm the underlying bed condition directly, check power and settings before assuming a failed light assembly, and escalate any misleading safety indication appropriately.
That is successful troubleshooting.
