Electromagnetic Immunity (continued)
Immunity Test
IEC 60601
Test Level
Compliance Guidelines
61000-4-3:
Radiated RF 3 V/m 80 MHz
to 2.5 GHz 3 V/m 80 MHz to
2.5 GHz
d =1.17 * SQRT(P) 80 MHz to 800 MHz
d =2.33 * SQRT(P) 800 MHz to 2.5 GHz
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 fixed RF
transmitters, as deter-mined by an
electromagnetic site survey
1
, should be
less than the compliance level in each
frequency range
2
.
Interference may occur in the vicinity of
equipment marked with this symbol:
61000-4-6:
Conducted RF 3 V
RMS
150 kHz
to 80 MHz
3 V
RMS
150 kHz
to 80 MHz
Portable and mobile RF communications
equipment should be used no closer to
any part of the VelaShape III system,
including cables, than the recommended
separation distance calculated from the
equation applicable to the frequency of
the transmitter.
Recommended separation distance:
d =1.17 * SQRT(P)
(1) 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 VelaShape III system is used exceeds
the applicable RF compliance level above, the VelaShape III 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
VelaShape III system.
(2) Over the frequency range 150 kHz to 80 MHz, field strengths should be less
than 3 V/m.
Note
●
At 80 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.
