Class II
ZOLL R Series Defibrillator/Monitor
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.
Typical Failure Modes

Error message on the display
HighSymptoms: A named error on the display, function inhibited (defib, pacing, or a parameter).
Root cause: The R Series Service Manual lists each error and the technician action - a stuck key, a module, a cable, or a board.
Defibrillation / pacing energy delivery fault
HighSymptoms: Will not charge / pace, charges slowly, or delivered energy fails the analyser test.
Root cause: HV charging circuit, capacitor, or the therapy-cable / paddle path.
Battery will not hold charge / not recognised
HighSymptoms: Short run time, low-battery early, battery-fault indication.
Root cause: Aged SurePower battery pack, or a charging-system fault.
Parameter fault (ECG / SpO2 / NIBP / EtCO2)
MediumSymptoms: Noisy or absent trace, no reading, NIBP times out.
Root cause: Worn patient cable / sensor, or a parameter-module fault.
Printer fault
LowSymptoms: No or faint strip, paper jam.
