Table 4 Guidance and MANUFACTURER's declaration – electromagnetic IMMUNITY for
ME EQUIPMENT and ME SYSTEMS that are not LIFE-SUPPORTING
Guidance and manufacturer's declaration – electromagnetic immunity
The device is intended for use in the electromagnetic environment specified below.
The customer or the user of the device should assure that it is used in such an environment.
IMMUNITY test
IEC 60601 TEST LEVEL
3 Vrms
Conducted RF
150 kHz to
IEC 61000-4-6
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.
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 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 device is used exceeds the applicable RF com-
pliance level above, the device should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary,
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3V/m.
Compliance level
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.
Recommended separation distance
3 Vrms
where P is the maximum output power rating of the transmitter in
3 V/m
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, 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:
such as re-orienting or relocating the device.
