SPECIFICATIONS
Guidance and manufacturer's declaration - electromagnetic immunity
The table is intended for use in the electromagnetic environment specified below. The customer or the user of the
table should assure that it is used in such an environment.
Immunity Test
IEC 60601 test level
Conducted RF
3 Vrms
IEC 61000-4-6
150 kHz to 80 MHz
Radiated RF
3 V/m
IEC 61000-4-3
80 MHz to 2,5 GHz
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.
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios,
a
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 table is used exceeds the applicable RF compliance level above, the table should be
observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-
orienting or relocating the table
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
b
Compliance level
Portable and mobile RF communications equipment
should be used no closer to any part of the table, includ-
ing 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
d = 2.3 √ P
3Vrms
Where P is the maximum output power rating of the trans-
mitter in watts (W) according to the transmitter manufac-
turer and d is the recommended separation distance in
3V/m
meters (m).
Field strengths from fixed RF transmitters, as deter-mined
by an electromagnetic site survey,
the compliance level in each frequency range.
Interference may occur in the vicinity of equipment
