Class II
ZOLL R Series Defibrillator/Monitor
ZOLL Medical · Model R Series ALS
Uniform Operating System between the two models Shares common electrodes, cables, paddles, and batteries Only one therapy cable needed for defibrillation, cardioversion and pacing no separate 3 lead cable required. Real CPR Help® to coach to the proper compression rate and depth during CPR as well as See-Thru CPR® to minimize pauses during CPR compressions The only defibrillator that recognizes the OneStep Pediatric electrode and automatically lowers the energy setting to 50J to prevent accidental overdose of energy Defibrillator event documentation via internal memory, as well as a removable Compact Flash card for easy data transfer and archiving. Conducts an automated self-test once a day. Patented external pacing offers superior capture at lower mean thresholds, reducing muscle artifact and ensuring more patient comfort and better patient tolerance
Key tips
- ·Never skip the daily/shift ready-check - a defibrillator found dead during a code is a real, repeated root-cause finding.
- ·Pads and batteries have real expiration dates - check them on every PM, not just at annual service.
- ·Verify energy-delivery accuracy with a real defibrillator analyzer, not just a self-test pass.

Troubleshooting Approach
A structured starting point derived from the failure modes above. Follow the manufacturer's service documentation for the actual procedure.
Symptom: High-voltage capacitor failure
- Confirm the presentation - typically charge fails or sluggish, low-energy delivery - and note the exact alarm or message and the conditions when it occurs.
- Check the most likely cause first: capacitor aging / leakage.
- Isolate the affected subsystem using the manufacturer's functional check or self-test, where one is provided.
- If the fault is confirmed and not a field adjustment, service or replace the rechargeable battery pack per the manufacturer's service documentation.
- Return the device to service only after the manufacturer's functional and applicable electrical-safety checks pass.
- Record the findings, any parts used, and the verification results in the maintenance history.
