Electrical Safety
This equipment is categorized as a Class I device with Type BF or Type CF (ECG) applied parts.
Prevention of Electric Shock
In a hospital environment, dangerous electric current may occur as a result of the potential difference between a contactable conductive part and connected equipment in treatment rooms. 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.
[Figure 1.1 Equipotential Bonding]
Additional equipment connected to medical electrical equipment must comply with the pertinent IEC standards (e.g. IEC 60950/EN 60950 for data processing equipment, IEC 60601-1/EN 60601-1 for medical devices). Furthermore, all components of the product shall comply with the requirements for medical electrical systems IEC 60601-1-1/EN 60601-1-1. Any person connecting additional equipment to the signal input and output ports of medical electrical equipment must verify that the equipment complies with IEC 60601-1-1/EN 60601-1-1.

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 buildup 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.
|
■ |
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. |
|
|
■ |
Always perform the pre-ESD preventive procedures before using |
|
CAUTION |
|
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. |
|
■ |
It is highly recommended that the user be given training on ESD-related |
|
|
|
warning symbols and preventive procedures. |

Chapter 1 Safety 1 - 11
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. |

80MHz to 800MHz 
800MHz to 2.5GHz
Where P is the transmitter’s maximum output power rating in watts (W) according to the transmitter’s manufacturer, and d is the recommended separation distance in meters
(m).
Field strengths from fixed RF transmitters, as determined by an electromagnetic site survey, ashould be less than the compliance level in each frequency range.b
Interference may occur in the vicinity of equipment marked with the following symbol:
Note 1) At 80MHz and 800MHz, the higher frequency range applies.
Note 2) These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects and people.
aField strengths from fixed transmitters, such as base stations for radio, (cellular/cordless) telephones and land mobile radios, amateur radio, AM and FM radio broadcasts and TV broadcasts cannot be predicted with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength, in the location in which the Ultrasound System is used, exceeds the applicable RF compliance level above, the Ultrasound System should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the Ultrasound System or using a shielded location with a higher RF shielding effectiveness and filter attenuation.
bIOver the frequency range 150kHz to 80MHz, field strengths should be less than 3 V/m.
