Introduction

WARNING: DEFIBRILLATOR PRECAUTIONS - Do not come into contact with patients during defibrillation. Otherwise, serious injury or death could result. Patient signal inputs labeled with the CF and BF symbols with paddles are protected against damage resulting from defibrillation voltages. To ensure proper defibrillation protection, use only the recommended cables and leadwires. Proper placement of defibrillator paddles in relation to the electrodes is required to ensure successful defibrillation. WARNING: ELECTRODES - Polarizing electrods (stainless steel or silver constructed) may cause the electrodes to retain a residual charge after defibrillation. A residual charge will block acquisition of the ECG signal. Whenever patient defibrillation is a possibility, use non-polarizing electrodes (silver or silver chloride construction) for ECG monitoring. WARNING: MAGNETIC AND ELECTRICAL INTERFERENCE - Magnetic and electrical fields are capable of interfering with the proper performance of the device. For this reason, make sure that all external devices operated in the vicinity of the device comply with the relevant EMC requirements. X-ray equipment or MRI devices are possible sources of interference as they may emit higher levels of electromagnetic radiation. WARNING: EXPLOSION HAZARD - Do NOT use in the presence of flammable anesthetics vapors or liquids. WARNING: INTERPRETATION HAZARD - Computerized interpretation is only significant when used in conjunction with clinical findings. A qualified physician must overread all computer-generated tracings. WARNING: OPERATOR - Medical technical equipment such as this system must be used only by qualified and trained personnel. WARNING: SHOCK HAZARD - Improper use of this device presents a shock hazard. Strictly observe the following guidelines. Failure to do so may endanger the lives of the patient, user, and bystanders. When disconnecting the device from the power line, remove the plug from the wall outlet before disconnecting the cable from the device; otherwise, there is a risk of coming into contact with line voltage by inadvertently introducing metal parts in the sockets of the power cord. Devices may be connected to other devices or to parts of systems only after making certain that there is no danger to the patient, operators, or environment as a result. Standards IEC 60601–1–1/EN60601–1–1 must be complied with in all cases.
