✅ 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.
