What This Guide Helps With
Addresses failure of the FRx to provide voice prompts or audio guidance, focusing on battery, pad cartridge, speaker function, and external settings.
Step-by-Step Troubleshooting
Ensure Patient Safety
Confirm the defibrillator is not in active use. If a patient requires resuscitation, use an alternate AED immediately.
Check Battery Connection and Status
- Remove and reseat the battery.
- Verify battery is fully charged and recognized (status light green).
- Poor battery contact can prevent audio circuits from powering.
Inspect Pad Cartridge
- Remove and reseat the electrode pads cartridge.
- Ensure cartridge is the correct model and fully connected.
- Pads not detected can inhibit voice prompts during self-test.
Perform Device Self-Test
- Power the AED on without pads attached (if allowed).
- Listen for any initial audio prompt.
- Note whether the self-test passes or fails; a failure may indicate internal or speaker fault.
Check Volume Settings
- Locate the volume control on the FRx (if available).
- Ensure it is not muted or set too low.
Inspect for Obstructions or Damage
- Examine speaker grill for debris, dust, or moisture.
- Check for cracks or physical damage that could prevent sound.
Test with Known Good Battery and Pads
- Swap in a confirmed functional battery and pad cartridge.
- Power on and listen for voice prompts.
- If audio activates, original battery or pad cartridge may be faulty.
If the Problem Persists
Common external causes have been ruled out. Device should be removed from service. Label as Out of Service and send for repair or bench evaluation. Do not attempt internal board-level repair; speaker and audio circuits require factory service.
Clinical Use Tip
Never attempt patient resuscitation testing with an active patient. Move the patient to a known working AED if voice prompts are not functional.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"AED voice prompts not activating during self-test."
Cause
What was observed during troubleshooting.
Example:
"Battery and/or pad cartridge not providing proper contact or internal speaker fault suspected."
Resolution
What action was taken.
Example:
"Device removed from service; battery and pads tested; unit labeled Out of Service and sent for repair."
Helpful Details to Include (If Known)
- Battery tested and recognized: Yes/No
- Pad cartridge tested and recognized: Yes/No
- Self-test result: Pass/Fail
- Speaker integrity observed: Any unusual sounds or obstruction noted
- Device status after troubleshooting: Out of Service
Final Thought
Voice prompt failure can delay critical patient response. Always confirm external factors first—battery, pads, settings—before escalating. Proper documentation ensures traceability and patient safety.
That is successful troubleshooting.
