Salient Operation Manual
Immunity test IEC 60601-1-2 test compliance level Electromagnetic environment guidance
Portable and mobile RF communication equipment should be
used no closer to any part of the Salient contrast injector than the
recommended separation distance calculated from the equation
applicable to the frequency of the transmitter.
Recommended separation distance:
Conducted RF
IEC 61000-4-6
3 Vrms at 1kHz 80% AM
150 kHz to 80 MHz
d = 1.2√P
Radiated RF
IEC 61000-4-3
3 V/m at 1kHz 80% AM
80 MHz to 2.7GHz
Proximity Fields
385 – 5785 MHz, 9 – 27 V/m
d = 1.2√P 80 MHz to 800 MHz
d = 2.3√P 800 MHz to 2.7GHz
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 metres (m).
Field strengths from fixed RF transmitters, as determined by an
electromagnetic site survey,
a
should be less than the compliance
level in each frequency range.
b
Interference may occur in the vicinity of equipment marked with
this symbol:
NOTE 1
NOTE 2
At 80 MHz and 800 MHz, the higher frequency range applies.
These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and
reflection from structures, objects and people.
a
Field strengths from fixed 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 fixed RF transmitters, an electromagnetic
site survey should be considered. If the measured field strength in the location in which the injector is used
exceeds the applicable RF compliance level above, the injector should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or
relocating the injector.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
