✅ Check the simple stuff first
  1. Make sure the patient is safe — swap in a backup unit if you need to.
  2. Reproduce the complaint yourself and write down exactly what you see (screen, alarm, code).
  3. Check power, battery, cables, accessories, and settings before ordering parts.
  4. Then open the service manual above and follow its troubleshooting section.
🧰 Common checks for Defibrillators (1)

Won't charge or deliver shock source ↗

  • Isolate controls: try paddles vs. pads vs. front-panel buttons
  • Check pad/paddle contact and cables (impedance disarm)
  • Check battery / run on AC; slow charge often = battery
  • Read stored failure codes in service mode before replacing therapy module
