Guidance and manufacturer’s declaration – electromagnetic immunity
The device is intended for use in the electromagnetic environments
listed below, and should only be used in such environments:
IMMUNITY
TEST
IEC 60601 TEST
LEVEL
COMPLIANCE
LEVEL
ELECTROMAGNETIC
ENVIRONMENT – GUIDANCE
Conducted RF
IEC 61000-4-6
3V rms
At 0.15-80 MHz
6V rms
At ISM & Radio
Amateur Freq.
3V rms
At 0.15-80 MHz
6V rms
At ISM & Radio
Amateur Freq.
Portable and mobile RF
communications equipment
should be used no closer to
any part of the device, including
cables, than the recommended
separation distance calculated
from the equation applicable
to the frequency of the
transmitter.
Radiated RF
IEC 61000-4-3
(Proximity
fields from
RF wireless
communications
equipment
IEC 61000-4-3)
10 V/m at 80-2700
MHz
AM Modulation
And 9-28V/m at
385-6000MHz,Pulse
Mode and other
Modulation. The
system shall be
tested as specified
in IEC60601-
1-2 Table 9 for
proximity fields
from RF wireless
communications
equipment using
the test methods
specified in IEC
61000-4-3
Recommended separation
distance
Considering to reduce the
minimum separation distance,
based on RISK MANAGEMENT,
and using higher IMMUNITY
TEST LEVELS that are
appropriate for the reduced
minimum separation distance.
Minimum separation distances
for higher IMMUNITY TEST
LEVELS shall be calculated
using the following equation:
E=6/d √ P
where P is the maximum
power in W, d is the minimum
separation distance in m, and E
is the IMMUNITY TEST LEVELS
in V/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 the following symbol:
10 V/m at 80-2700
MHz
AM Modulation
And 9-28V/m at
385-6000MHz,Pulse
Mode and other
Modulation. The
system shall be
tested as specified
in IEC60601-1-2

methods specified in
IEC 61000-4-3
