Introduction: Safety information

Safety information Responsibility of the manufacturer GE is responsible for the effects of safety, reliability, and performance only if: 

Assembly operations, extensions, readjustments, modifications, or repairs are carried out by persons authorized by GE.



The electrical installation of the relevant room complies with the requirements of the appropriate regulations.



The equipment is used in accordance with the instructions for use.

General This device is intended for use under the direct supervision of a licensed health care practitioner. This device is not intended for home use. Federal law restricts this device to be sold by or on the order of a physician. Contact GE for information before connecting any devices to the equipment that are not recommended in this manual. Parts and accessories used must meet the requirements of the applicable IEC 60601 series safety standards, and/or the system configuration must meet the requirements of the IEC 60601-1-1 medical electrical systems standard. Periodically, and whenever the integrity of the device is in doubt, test all functions. The use of accessory equipment not complying with the equivalent safety requirements of this equipment may lead to a reduced level of safety of the resulting system. Consideration relating to the choice shall include: 

use of the accessory in the patient vicinity; and



evidence that the safety certification of the accessory has been performed in accordance to the appropriate IEC 60601-1 and/or IEC 60601-1-1 harmonized national standard.

If the installation of the equipment, in the USA, will use 240V rather than 120V, the source must be a center-tapped, 240V, single-phase circuit.

Introduction: Equipment symbols

Equipment symbols NOTE: Some symbols may not appear on all equipment. ATTENTION: Consult accompanying documents before using the equipment. In Europe, this symbol means dangerous or high voltage. In the United States, this symbol represents the caution notice below: To reduce the risk of electric shock, do not remove cover (or back). Refer servicing to qualified personnel. Defibrillator-proof type CF equipment; type CF equipment is specifically designed for applications where a conductive connection directly to the heart is established. The paddles indicate the equipment is defibrillator proof. Defibrillator-proof type BF equipment; type BF equipment is suitable for intentional external and internal application to the patient, excluding direct cardiac application. Type BF equipment is type B equipment with an F-type isolated (floating) part. The paddles indicate the equipment is defibrillator proof. Type B equipment; type B equipment is suitable for intentional external and internal application to the patient, excluding direct cardiac application.

Equipotential Stud: A ground wire from another device can be tied here to ensure the devices share a common reference.

Introduction: Equipment symbols NOTE The following symbols (required by China law only) are representative of what you may see on your equipment. The number in the symbol indicates the EFUP period in years, as explained below. Check the symbol on your equipment for its EFUP period. This symbol indicates the product contains hazardous materials in excess of the limits established by the Chinese standard SJ/T11363-2006 Requirements for Concentration Limits for Certain Hazardous Substances in Electronic Information Products. The number in the symbol is the Environment-friendly User Period (EFUP), which indicates the period during which the toxic or hazardous substances or elements contained in electronic information products will not leak or mutate under normal operating conditions so that the use of such electronic information products will not result in any severe environmental pollution, any bodily injury or damage to any assets. The unit of the period is “Year”. In order to maintain the declared EFUP, the product shall be operated normally according to the instructions and environmental conditions as defined in the product manual, and periodic maintenance schedules specified in Product Maintenance Procedures shall be followed strictly. Consumables or certain parts may have their own label with an EFUP value less than the product. Periodic replacement of those consumables or parts to maintain the declared EFUP shall be done in accordance with the Product Maintenance Procedures. This product must not be disposed of as unsorted municipal waste, and must be collected separately and handled properly after decommissioning. This symbol indicates that this electronic information product does not contain any toxic or hazardous substance or elements above the maximum concentration value established by the Chinese standard SJ/T11363-2006, and can be recycled after being discarded, and should not be casually discarded.
