SAFETY SAFETY
Electrical This product is intended to be operated from a mains power source of nominally 100, 120, 220 and 230V~. The correct mains operating power voltage is specified on the monitor’s rear panel. WARNING: To prevent electrical hazards to all personnel, this monitor must be properly grounded. Connect the monitor only to a three-wire, grounded, hospital grade receptacle. The three-conductor plug must be inserted into a properly wired three-wire receptacle; if a three-wire receptacle is not available, a qualified electrician must install one in accordance with the governing electric code. WARNING: Do not under any circumstances remove grounding conductor from the power plug. WARNING: The power cable supplied with this equipment provides for this protection. Do not attempt to defeat this protection by modifying the cable or by using ungrounded adapters or extension cables. The power cord and plug must be intact and undamaged. To disconnect the equipment from the mains power unplug the power cord. WARNING: Do not connect to an electrical outlet controlled by a wall switch or dimmer. WARNING: If there is any doubt about the integrity of the protective ground conductor arrangement, do not operate the monitor until the AC power source protective conductor is fully functional. WARNING: Do not place the monitor in any position that may cause it to fall on the patient. Do not lift the monitor by the power supply cord or patient cable. WARNING: Electric shock hazard! Do not remove covers or panels. Refer service to qualified service personnel. WARNING: To avoid electrical shock, disconnect the monitor from its power source before changing fuses. Replace fuses only with same type and rating (see fuse ratings). WARNING: Do not clean monitor while it is on and/or plugged into a power source. WARNING: If unit is accidentally wet, discontinue use until dry and then test unit for proper operation before reuse on a patient. WARNING: This unit uses a common isolation path for the ECG leads. Do not connect any non-isolated accessories to the ECG input when connected to a patient, as this may compromise the safety of the unit. When attached to other devices, insure that the total chassis leakage currents of all units do not exceed 300 μA.
Explosion DANGER: Explosion hazard! Do not use this equipment in the presence of flammable anesthetics or other flammable substance in combination with air, oxygen-enriched environment or nitrous oxide.

SAFETY
Patient Connections Patient connections are electrically isolated. For all connections use isolated probes. Don’t let patient connections contact other conductive parts, including ground. See instructions for patient connections in this manual. Carefully route patient cables to reduce the possibility of patient entanglement or strangulation. Leakage current is limited internally by this monitor to less than 10 μA. However, always consider cumulative leakage current that can be caused by other equipment used on the patient at the same time as this monitor. To ensure that the leakage current protection remains within the specifications, use only the patient cables specified in this manual. This monitor is supplied with protected lead wires. Do not use cables and leads with unprotected lead wires having exposed conductors at the cable end. Unprotected lead wires and cables may pose an unreasonable risk of adverse health consequences or death. Line isolation monitor transients may resemble actual cardiac waveforms and thus inhibit heart rate alarms. To minimize this problem, ensure proper electrode placement and cable arrangement. If an alarm condition occurs while the alarms are set to off, neither visual or audio alarms will be present.
MRI The model 101R/NR should not be used within the magnetic field during Magnetic Resonance Imaging.
Pacemakers Rate meters might continue to count the pacemaker rate during occurrences of cardiac arrest or some arrhythmias. Do not rely on rate meter alarms. Keep pacemaker patients under close surveillance.
Electrosurgery Protection This equipment is protected against electrosurgery potentials To avoid the potential of electrosurgery burns at monitoring sites, ensure proper connection of the electrosurgery return circuit as described by the manufacturer’s instructions. If improperly connected, some electrosurgery units might allow energy to return through the ECG electrodes.
Defibrillation Protection This equipment is protected against 360 J defibrillator discharge.. The monitor is internally protected to limit current through the electrodes to prevent injury to the patient and damage to the equipment as long as the defibrillator is used in conformance with the manufacturer’s instructions.
EMC This equipment has been certified to be protected to emissions and immunity according to IEC-60601-1-2.
Disposal of Biohazard Materials Disposal of Biohazard Materials must be done in accordance to local, state, and federal laws and regulations. NOTE: See each section for additional warnings and cautions.

Safety Considerations
Disposable products are intended for single-use only. Do not attempt to re-use these products. Patient connections are electrically isolated Type CF ⎯⏐ ♥ ⏐⎯. For all connections use insulated probes. Don't let patient connections contact other conductive parts, including earth. See instructions for patient connections in this manual. Leakage current is limited internally by this monitor to less than 10 μA. However, always consider additional leakage current that can be caused by other equipment used on the patient at the same time as this monitor. Avoid electrosurgery burns at monitoring sites by ensuring proper connection of the electrosurgery return circuit. If improperly connected, some electrosurgery units might allow energy to return through the electrodes. Rate meters might continue to count the pacemaker rate during occurrences of cardiac arrest or some arrhythmias. Do not rely on rate meter alarms. Keep pacemaker patients under close surveillance.
