EMC RELATED CAUTION This equipment and/or system complies with the International Standard IEC60601-1-2 for electromagnetic compatibility for medical electrical equipment and/or system. However, an electromagnetic environment that exceeds the limits or levels stipulated in the IEC60601-1-2, can cause harmful interference to the equipment and/or system or cause the equipment and/or system to fail to perform its intended function or degrade its intended performance. Therefore, during the operation of the equipment and/or system, if there is any undesired deviation from its intended operational performance, you must avoid, identify and resolve the adverse electromagnetic effect before continuing to use the equipment and/or system. The following describes some common interference sources and remedial actions: 1.

Strong electromagnetic interference from a nearby emitter source such as an authorized radio station or cellular phone: Install the equipment and/or system at another location if it is interfered with by an emitter source such as an authorized radio station. Keep the emitter source such as cellular phone away from the equipment and/or system.

2.

Radio-frequency interference from other equipment through the AC power supply of the equipment and/or system: Identify the cause of this interference and if possible remove this interference source. If this is not possible, use a different power supply.

3.

Effect of direct or indirect electrostatic discharge: Make sure all users and patients in contact with the equipment and/or system are free from direct or indirect electrostatic energy before using it. A humid room can help lessen this problem.

4.

Electromagnetic interference with any radio wave receiver such as radio or television: If the equipment and/or system interferes with any radio wave receiver, locate the equipment and/or system as far as possible from the radio wave receiver.

1. GENERAL

Important Safety Information General DANGER • Never use the defibrillator in a flammable atmosphere (i.e. areas with flammable anesthetics, concentrated oxygen, hyperbaric oxygen) or in an environment in which an electrical arc could ignite an explosion. Otherwise, the defibrillator will explode or fire. • Never use the defibrillator in a high-pressure oxygen medical care tank. Otherwise, the defibrillator will explode or fire.

WARNING • The defibrillator generates high voltage. The defibrillator must only be operated by trained and qualified medical personnel. • Radiofrequency or Electromagnetic Field Do not use any kind of non-essential non-patient care device within a radius of 1 meter around the defibrillator. The use of non-essential non-patient care devices that emit radiofrequency or electromagnetic fields may interfere with the operation of the defibrillator by causing noise on the ECG waveform or error messages. If a non-essential non-patient care device is accidentally placed near the defibrillator, quickly remove it. • MRI examination - Do not install this defibrillator in an MRI examination room. The defibrillator may not operate properly due to high-frequency magnetic noise from the MRI. - When performing MRI tests, remove all electrodes and transducers from the patient which are connected to this defibrillator. Failure to follow this warning may cause serious electrical burn on the patient due to local heating caused by dielectric electromotive force. For details, refer to the instruction manual for the MRI. • Using with ESU - When using this defibrillator with an ESU, the ESU return plate and the electrodes for monitoring must be firmly attached to the patient. If the return plate is not attached correctly, it may burn the patient’s skin where the electrodes are attached. Refer to the instruction manual for the ESU. - When using an ESU, use this defibrillator only in the MONITOR mode and use the ECG electrodes for monitoring. Do not monitor ECG with disposable pads, external paddles or internal paddles. Otherwise, high frequency energy from the ESU causes abnormal current to flow in the patient and unexpected discharge. This causes serious electrical burn, shock, or other injury and damages the defibrillator.
