What This Guide Helps With

Troubleshooting failed automatic self-tests, absent readiness indication, recurring attention alerts, or not-ready status caused by battery, electrodes, accessories, or device faults.

Step-by-Step Troubleshooting

1. Ensure Patient Safety First

Do not troubleshoot a LIFEPAK CR2 with an unresolved self-test or readiness failure while it is being relied upon for emergency response.

Immediately provide another verified, rescue-ready AED or defibrillator for the coverage area before continuing troubleshooting.

Expected: Emergency response capability remains available while the affected CR2 is evaluated.

Why it matters: A failed self-test or not-ready condition means Clinical Engineering should not assume the AED will perform reliably during a cardiac emergency.

If alternate emergency coverage is established, continue troubleshooting in a controlled Clinical Engineering setting.

2. Confirm the Exact Readiness Condition

Observe the device without relying only on the staff description.

Check for:

The LIFEPAK CR2 normally uses its readiness indication to communicate device status and performs automatic self-testing.

Expected: Clinical Engineering determines whether the complaint is a current not-ready condition, an intermittent alert, or a historical report.

If the readiness indication is normal and the complaint cannot be reproduced, continue checking battery, electrodes, history, and physical condition before returning the AED to service.

3. Check for Recent Use or Interrupted Post-Use Restoration

Determine whether the AED was recently:

Inspect for incomplete restoration after use.

Expected: The AED is fully restored with correct components installed and no obvious post-use condition explains the readiness failure.

If restoring the device correctly returns it to verified ready status, document the cause and stop.

4. Inspect the Battery Externally

Examine the installed battery and battery area for:

Do not use a damaged or suspect battery.

Expected: The correct battery is present, intact, and properly installed.

If a battery condition is found and replacement with an approved known-good battery restores normal readiness status, document the finding and stop.

5. Reseat the Battery Using the Approved External Method

With the AED removed from clinical service, inspect and reseat the battery according to approved device handling practices.

After reseating:

Expected: The battery remains securely installed and the device returns to normal ready indication.

If normal readiness is restored and remains stable, complete final verification, document the correction, and stop.

6. Inspect the QUIK-STEP Electrodes

Check the installed electrode assembly for:

Do not assume a self-test failure is internal until the installed consumable condition has been verified.

Expected: Correct, unopened, unexpired, undamaged LIFEPAK CR2-compatible electrodes are properly installed.

If replacing a defective or expired electrode set restores verified ready status, document the cause and stop.

7. Inspect the Lid and External Housing

Check the CR2 for:

Pay particular attention when the complaint began after transport, a drop, or repeated cabinet handling.

Expected: The enclosure and lid operate normally with no visible physical condition that could affect device readiness.

If physical damage is present, remove the AED from service rather than continuing operational testing.

8. Check for Known Battery-Depletion Clues

Determine whether the device has:

Inspect for unusual circumstances that may have caused premature battery depletion.

Expected: Clinical Engineering distinguishes a one-time depleted battery condition from a recurring device-related readiness problem.

If a known-good approved battery also develops abnormal behavior or the not-ready condition returns, stop repeated battery substitution and escalate.

9. Review Connected Readiness Information When Available

For connected CR2 installations, review the applicable device-management system for:

Stryker supports remote readiness monitoring and status notification for connected LIFEPAK CR2 deployments.

Expected: Remote information either supports the local finding or identifies a separate connectivity or stale-status concern.

If the physical AED is ready but the remote system alone reports outdated status, troubleshoot the connectivity issue separately rather than labeling the AED itself as a confirmed self-test failure.

10. Perform a Controlled Power-On Observation

With the AED off patient and alternate emergency coverage available, activate the device and observe:

Do not connect the AED to a patient for troubleshooting.

Expected: The device starts normally without persistent abnormal behavior.

If power-on behavior is abnormal or the device cannot establish normal readiness afterward, remove it from service.

11. Recheck Readiness After External Causes Are Corrected

After correcting any verified external issue:

Expected: The AED demonstrates stable ready status with no recurring attention indication.

If the readiness failure returns, do not repeatedly clear or cycle the device in an attempt to force a ready indication.

12. Stop When the Failure Cannot Be Cleared Externally

If the CR2 remains not ready after:

Treat the condition as a likely internal device, self-test, sensing, power-management, or control fault.

Expected: Clinical Engineering stops before unsupported internal disassembly or board-level troubleshooting.

If the Problem Persists

Common external causes have been ruled out, and the automatic self-test or readiness failure is likely internal.

The device should be:

Do not return the LIFEPAK CR2 to emergency coverage based only on intermittent recovery, a temporary disappearance of an alert tone, or an unverified power cycle.

Knowing when to stop is proper troubleshooting. A defibrillator with unresolved readiness status should not be assumed dependable for rescue use.

Clinical Use Tip

Never troubleshoot an unresolved self-test failure while the LIFEPAK CR2 is the only available AED for an active patient or response area.

Move emergency coverage to another verified device first. Troubleshoot only when safe, and do not connect a patient solely to test whether the AED functions.

Work Order Documentation (CCR Method)

CCR = Complaint, Cause, Resolution

Complaint

What was reported by the clinical staff.

Example:
"Clinical staff reported the LIFEPAK CR2 failed its automatic readiness check and the normal readiness indicator was not flashing."

Cause

What was observed during troubleshooting.

Example:
"Inspection found the installed battery was not maintaining normal device readiness; the not-ready condition cleared after installation of an approved known-good replacement battery."

Resolution

What action was taken.

Example:
"Replaced the battery, verified electrodes and external condition, confirmed normal startup and stable ready indication, and returned the AED to service."

Helpful Details to Include (If Known)

Final Thought

A LIFEPAK CR2 automatic self-test failure should be approached as a readiness concern, not immediately assumed to be an internal board failure. Protect emergency coverage first, then verify the battery, electrodes, recent-use restoration, enclosure condition, and readiness status logically. When external causes are ruled out and normal readiness cannot be established, remove the AED from service and escalate appropriately. Clear CCR documentation preserves both patient safety and maintenance history.

That is successful troubleshooting.
