Electrical Safety

This equipment has been verified as a Class I device with Type BF applied parts.

CAUTION:

X

As for US requirement, the LEAKAGE CURRENT might be measured from a center-tapped circuit when the equipment connects in the United States to 240V supply system.

X

To help assure grounding reliability, connect to a “hospital grade” or “hospital only” grounded power outlet.

Prevention of Electric Shock

Chapter 1 Safety

In a hospital environment, hazardous current can form due to potential differences between exposed conductive parts and connected devices. The solution to the problem is consistent equipotential bonding. Medical equipment is connected with connecting leads made up of sockets which are angled to the equipotential bonding network in medical rooms.

Operation Manual

Additional equipment connected to medical electrical equipment must comply with the respective IEC or ISO standards (e.g. IEC 60950 for data-processing equipment). Furthermore, all configurations must comply with the requirements for medical electrical systems (see IEC 60601-1-1 or clause 16 of the 3rd Ed. of IEC 60601-1, respectively). Anybody connecting additional equipment to medical electrical equipment configures a medical system and is therefore responsible for the system complying with the requirements for medical electrical systems.

WARNING:

X

Electric shock may result if this system, including all of its externally mounted recording and monitoring devices, is not properly grounded.

X

Never remove the cover from the product. Hazardously high voltage flows through the product. All internal adjustments and replacements must be made by a qualified Samsung Medison Customer Service Department.

X

Always check the product’s casing, cables, cords, and plugs for damage before using the product. Disconnect and do not use the power source if the face is cracked, chipped, torn, the housing is damaged, or if the cable is abraded.

X

Always disconnect the system from the wall outlet prior to cleaning it.

X

All patient contact devices, such as probes and ECG leads, must be removed from the patient prior to the application of a high voltage defibrillation pulse.

X

The use of flammable anesthetic gas or oxidizing gases (N2O) should be avoided. Doing so may cause an explosion.

X

Avoid placing the system where it is likely to be difficult to operate, or disconnect.

X

Do not use HF surgical equipment with the system. Any malfunctions in the HF surgical equipment may result in burns to the patient.

X

The System must only be connected to a supply mains with protective earth to avoid risk of electric shock.

1-10

CAUTION:

X

The system has been designed for 100-120VAC and 200-240VAC; you should select the input voltage of the printer and VCR. Prior to connecting a peripheral power cord, verify that the voltage indicated on the power cord matches the voltage rating of the peripheral device.

X

An isolation transformer protects the system from power surges. This continues to operate when the system is on standby.

X

Do not immerse the cable in liquids. Cables are not waterproof.

X

The auxiliary socket outlets installed on this system are rated 100-120V and 200-240V, with a maximum total load of 150VA. Only use these outlets for supplying power to equipment that is intended to be part of the ultrasound system. Do not connect additional multiple-socket outlets or extension cords to the system.

X

Do not connect any peripheral devices not listed in this manual to the auxiliary socket outlets of the system.

X

Do not touch SIP/SOP and the patient simultaneously. There is a risk of electric shock from current leakage.

Chapter 1 Safety

ECG-Related Information

WARNING:

X

This product does not support ECG monitoring. Therefore, it will not recognize incompatible ECG signals.

X

Do not use the ECG electrodes of HF surgical equipment. Any malfunctions in the HF surgical equipment may result in burns to the patient.

X

Do not use ECG electrodes during cardiac pacemaker procedures or other electrical stimulators.

X

Do not use ECG leads and electrodes in an operating room.

ESD

Electrostatic discharge (ESD), commonly referred to as a static shock, is a naturally occurring phenomenon. ESD is most prevalent during conditions of low humidity, which can be caused by heating or air conditioning. The static shock, or ESD, is a discharge of the electrical energy build-up from a charged individual to a lesser or uncharged individual or object. An ESD occurs when an individual with an electrical energy build-up comes in to contact with conductive objects such as metal doorknobs, file cabinets, computer equipment, and even other individuals.

CAUTION:

X

The level of electrical energy discharged from a system user or a patient to an ultrasound system can be significant enough to cause damage to the system or probes.

X

Always perform the pre-ESD preventive procedures before using connectors marked with the ESD warning label.

− Apply anti-static spray to carpets or linoleum.

− Use anti-static mats.

− Ground the product to the patient table or bed.

X

It is highly recommended that the user be given training on ESD-related warning symbols and preventive procedures.

1-11

Operation Manual

EMI

This product complies with EMI (Electromagnetic Interference) standards. However, using the system inside an electromagnetic field can lower the quality of ultrasound images and even damage the product.

If this occurs often, Samsung Medison suggests a review of the environment in which the system is being used, to identify possible sources of radiated emissions. These emissions could be from other electrical devices used within the same room or an adjacent room. Communication devices, such as cellular phones and pagers, can cause these emissions. The existence of radios, TVs, or microwave transmission equipment nearby can also cause interference.

CAUTION: In cases where EMI is causing disturbances, it may be necessary to relocate the system.

EMC

The testing for the EMC (Electromagnetic Compatibility) of this system has been performed according to the international standard for EMC with medical devices (IEC60601-1-2). This IEC standard was adopted in Europe as the European norm (EN60601-1-2).

Guidance and Manufacturer’s Declaration – Electromagnetic Emissions

This product is intended for use in the electromagnetic environment specified below. The customer or the user of this product should assure that it is used in such an environment.

Complies

The Ultrasound System uses RF energy only for its internal function. Therefore, its RF emissions are very low and are not likely to cause any interference in nearby electronic equipment.

The Ultrasound System is suitable for use in all establishments, including domestic establishments and those directly connected to the public low-voltage power supply network that supplies buildings used for domestic purposes.
