Electromagnetic Immunity for Medical Equipment not Life Supporting
The
MyLab
system is intended for use in the electromagnetic environment specified below. The customer or
the user of the
MyLab
system should assure that it is used in such an environment.
Immunity Test
IEC60601
Test Level Compliance
Level Electromagnetic Environment and
Measures to Be Taken
Conducted RF
IEC 61000-4-6 3 Vrms
150 kHz to 80
MHz 3 Vrms
150 kHz to 80
MHz Mobile or portable radio frequency (RF)
communication equipment should be used no
closer to any part of the
MyLab
system,
including cables, than the recommended
separation distance calculated from the
equation applicable to the frequency of the
transmitter.
Recommended separation distance
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 the following
symbol:
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 pre-
dicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF trans-
mitters, an electromagnetic site survey should be considered. If the measured field strength in the
location in which the
MyLab
system is used exceeds the applicable RF compliance level above, the
MyLab
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
MyLab
system.
b. b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
Radiated RF

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.
