What This Guide Helps With
A required Polaris 600 test, initialization check, or applicable calibration procedure cannot complete successfully.
Step-by-Step Troubleshooting
1. Protect the Patient and Remove the Light From Clinical Dependence
Do not perform service tests or calibration activities while the surgical light is required for patient care. Provide alternate verified illumination.
Expected outcome: Testing can proceed without jeopardizing surgical lighting.
2. Confirm the Exact Procedure That Failed
Determine whether the complaint involves a normal startup self-check, an approved service test, or a documented calibration procedure. Record displayed messages or abnormal indications exactly as observed.
Do not enter undocumented or unauthorized service functions.
Expected outcome: The failed process is clearly identified without assuming all test failures have the same cause.
3. Verify Normal Power and Startup
Confirm stable external power and allow the surgical light to complete its normal startup before repeating an approved test.
Expected outcome: The device reaches its normal operating state. If the test succeeds after correcting power or startup conditions, verify normal function and stop troubleshooting.
4. Inspect External Conditions
Check the light head and relevant external components for contamination, obstruction, damage, improperly installed accessories, or other conditions that could interfere with the applicable test.
Expected outcome: The equipment is clean, unobstructed, and properly assembled for the intended procedure.
5. Verify Required Positioning or Setup
If the approved test or calibration requires particular positioning, accessories, or external test equipment, confirm these are arranged according to the applicable manufacturer documentation.
Do not invent setup distances, limits, or target values.
Expected outcome: The test setup matches the approved procedure.
6. Inspect Accessible Connections
Verify accessible connections relevant to the test are fully seated and undamaged.
Expected outcome: No external connection problem is preventing completion. If correcting a connection allows the test to pass, verify function and stop troubleshooting.
7. Repeat the Approved Test Once Conditions Are Correct
Repeat only the authorized procedure after correcting external conditions. Avoid repeated cycling of a failing test without identifying a reason.
Expected outcome: The self-test or calibration completes successfully and the device functions normally. If so, troubleshooting is complete.
8. Escalate Repeated Test Failure
If the approved procedure still cannot complete with correct setup, stable power, and intact external connections, discontinue troubleshooting at the external level.
Expected outcome: The device is withheld from service pending qualified evaluation.
If the Problem Persists
External setup and environmental causes have been ruled out. Remaining possibilities may include sensors, internal electronics, stored configuration, software, or another service-level fault.
The affected equipment should be:
- Removed from service when the required test or calibration cannot be completed
- Labeled Out of Service
- Sent for repair or bench/on-site evaluation
- Evaluated using applicable manufacturer documentation and approved test equipment
- Calibrated, configured, or repaired only by qualified personnel
A failed required verification must not be bypassed simply because the light appears to illuminate.
Clinical Use Tip
A light that illuminates but cannot successfully complete a required verification is not automatically acceptable for clinical use.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Clinical Engineering found that the Polaris 600 would not complete an applicable functional verification after service."
Cause
What was observed during troubleshooting.
Example:
"Inspection found that an external accessory used with the test setup was not fully seated."
Resolution
What action was taken.
Example:
"Corrected the accessory connection, repeated the approved verification successfully, and confirmed normal surgical-light operation before return to service."
Helpful Details to Include (If Known)
- Exact test or calibration attempted
- Exact displayed message
- Power condition
- Test setup used
- Light-head position
- Accessories installed
- External test equipment used
- Connections inspected
- Repeat-test result
- Final device status
Final Thought
A failed verification deserves a logical investigation, not repeated resets or assumptions. Confirm power, setup, positioning, accessories, and connections first, then escalate unresolved failures and document the final verified condition.
That is successful troubleshooting.
