Guidance and manufacturer’s declaration – electromagnetic immunity
Interson’s USB Ultrasound Probes are intended for use in the electromagnetic environment specified below. The
customer or the user of the Interson USB Ultrasound Probe should ensure that it is used in such an environment.

– guidance
Portable and mobile RF communications
equipment should be used no closer to any part
of the product, including cables, than the
recommended separation distance calculated
from the equation applicable to the frequency of
the transmitter.
Recommended separation distance:
𝑑 = 1.2√𝑃
𝑑 = 1.2√𝑃
for 80 MHz to 800 MHz
𝑑 = 2.3√𝑃
for 800 MHz to 2.5 GHz
Where
P
is the maximum output power rating of
the transmitter in Watt (W) according to the
transmitter manufacturer and
d
is the
recommended separation distance in meters (m).
Field strengths from fixed RF transmitters, as
determined by an electromagnetic site survey a,
should be less than the compliance level b in
each frequency range
Interference may occur in
the vicinity of equipment
marked with this symbol.
NOTE 1: At 80 MHz and 800 MHz, 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.
a.
The ISM (industrial, scientific, and medical) bands between 150 kHz and 80 MHz are 66.765 MHz to
6.795 MHz; 13.553 MHz to 13.567 MHz; 26.957 MHz to 27.283 MHz; and 40.66 MHz to 40.70 MHz.
b.
The compliance levels in the ISM frequency bands between 150 kHz and 80 MHz and in the frequency
range 80 MHz to 2.5 GHz are intended to decrease the likelihood that mobile/portable communications
equipment could cause interference if it is inadvertently brought into patient areas. For this reason, an
additional factor of 10/3 has been incorporated into the formulae used in calculating the recommended
separation distance for transmitters in these frequency ranges.
c.
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and
land mobile radios, amateur radios, AM and FM radio broadcast and TV broadcast cannot be predicted
theoretically 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 USB Ultrasound Probe is used exceeds the applicable RF compliance level above, the USB
Ultrasound Probe should be observed to verify normal operation. If abnormal performance is observed,
additional measures may be necessary, such as re-orienting or relocating the USB Ultrasound Probe.
d.
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 1 V/m
