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

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

recommended separation distance in meters (m).

Field strengths from xed RF transmitters, as

determined by an electromagnetic site survey, a

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 [V1] V/m.
