Conducted RF

IEC 61000-4-6

3 Vrms

150 kHz

to 80MHz

0.01V Portable and mobile RF communications

equipment should be used no closer to any part

of the Ultrasound System, including cables, than

the recommended separation distance calculated

from the equation applicable to the frequency of

the transmitter.

Recommended separation distance

80MHz to 800MHZ

800MHz to 2.5GHz

Radiated RF

IEC 61000-4-3

3 V/m

80 MHz

to 2.5GHz

3V/m where P is the maximum output power rating

of the transmitter in watts (W) according to the

transmitter manufacturer and d is the recomm-

ended separation distance in meters (m).

Field strengths from xed RF transmitters, as

determined by an electromagnetic site survey,

should be less than the compliance level in each

frequency range.

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 aected by absorption

and reection from structures, objects and people.

Field strengths from xed transmitters, such as base stations for radio (cellular/cordless) telephones and land

mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically

with accuracy. To assess the electromagnetic environment due to xed RF transmitters, an electromagnetic

site survey should be considered. If the measured eld 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 re-orienting or relocating the Ultrasound System or using a shielded location with a higher RF shielding

eectiveness and lter attenuation.

Over the frequency range 150kHz to 80MHz, eld strengths should be less than [V

] V/m.
