Guidance and manufacturer's declaration -electromagnetic immunity (for all equipment and systems that are not life supporting)
The running machine is intended for use in the electromagnetic environment specified below. The customer or the user of the running machine 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, amateur radio, AM and FM
a
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 running machine is used
exceeds the applicable RF compliance level above, the running machine should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as reorienting or relocating the running machine.
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
b
Recommended separation distances between portable and mobile RF communications equipment and the running machine
(for all equipment and systems that are not life supporting)
The running machine is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user of
the running machine can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications
equipment (transmitters) and the running machine as recommended below, according to the maximum output power of the communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation distance d in meters (m) can be estimated using the
equation applicable to the frequency of the transmitter, where P is the maximum output power rating of the transmitter in watts (W) according to the
transmitter manufacturer.
NOTE 1: At 80 MHz and 800 MHz, the separation distance for 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.

Electromagnetic environment — guidance
Portable and mobile RF communications equipment should be
used no closer to any part of the running machine, including
cables, than the recommended separation distance calculated
from the equation applicable to the frequency of the transmitter.
Recommended separation distance:
d = 1.17 1/V * √P
d = 1.17 m/V * √P for 80 MHz to 800 MHz
d = 2.33 m/V * √P for 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 determined by an
electromagnetic site survey.
should be less than the compliance level in each frequency
