Do not use the unit in AED mode or advisory mode during patient movement. A patient must 
be motionless during ECG rhythm analysis. Do not touch the patient during analysis. If 
transporting the patient, cease all movement before beginning ECG analysis.
ECG rhythm analysis does not warn of patient asystole, which is not a shockable rhythm.
The ECG rhythm analysis function might not reliably identify ventricular fibrillation in the 
presence of an implanted pacemaker. Inspection of the electrocardiogram and clinical evidence 
of cardiopulmonary arrest should be the basis for any treatment of patients with an implanted 
pacemaker.
Implanted pacemakers might cause the heart rate meter to count the pacemaker rate during 
incidents of cardiac arrest or other arrhythmias. Dedicated pacemaker detection circuitry may 
not detect all implanted pacemaker spikes. Check the patient's pulse; do not rely solely on heart 
rate meters. Patient history and physical examination are important factors in determining the 
presence of an implanted pacemaker. Pacemaker patients should be carefully observed. 
Do not place electrodes directly over an implanted pacemaker.
The R Series unit detects ECG electrical signals only. It does not detect a pulse (effective 
circulatory perfusion). Always verify pulse and heart rate by physical assessment of the patient. 
Never assume that the display of a nonzero heart rate means that the patient has a pulse.
To avoid possible damage to the R Series unit, turn off pacing before defibrillating the patient 
with a second defibrillator.
Do not use the unit’s ECG-out signal as a synchronization pulse for another defibrillator or 
cardioverter.
Place the patient on a firm surface before performing CPR.
Battery
Although the device can operate with AC power alone, ZOLL strongly recommends that you 
operate the unit with a battery installed at all times. Operating the unit with a battery provides a 
backup in case of AC power shortage, and results in faster charge time. The battery can be 
automatically recharged while it is installed in the unit. Keep a fully charged spare battery pack 
with the defibrillator at all times.
Test battery packs regularly. A battery that does not pass the ZOLL charger’s capacity test 
might cause the R Series unit to shut down unexpectedly.
When the warning LOW BATTERY appears, plug the R Series unit into a power source or install 
a fully charged battery pack. When the warning REPLACE BATTERY appears, immediately 
replace the battery pack with a fully charged pack or plug the R Series unit into a power source, 
as unit shut down due to a low battery condition is imminent.
If mistreated, a battery pack might explode. Do not disassemble a battery pack or dispose of it 
in fire.
Operator Safety
Do not use R Series products in the presence of oxygen-rich atmospheres, flammable 
anesthetics, or other flammable agents (such as gasoline). Using the unit in such environments 
might cause an explosion.
Do not use the unit near or within standing water. Electrical safety might be compromised when 
the defibrillator is wet.
