Guidance and manufacturer's declaration — electromagnetic immunity
The MA 28 is intended for use in the electromagnetic environment specified below. The customer or the user of the MA 28 should
assure that it is used in such an environment,
Immunity test
IEC / EN 60601 test level
Conducted RF
3 Vrms
IEC / EN 61000-4-6
150kHz to 80 MHz
Radiated RF
3 V/m
IEC / EN 61000-4-3
80 MHz to 2,7 GHz
NOTE1 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 MA 28 is used exceeds the applicable RF compliance level above, the MA 28 should be observed to verify normal
operation, If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the MA 28.
b)
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

Electromagnetic environment – guidance
Compliance level
Portable and mobile RF communications
equipment should be used no closer to any
parts of the MA 28, including cables, than the
recommended separation distance calculated
from the equation applicable to the frequency
of the transmitter.
Recommended separation distance:
3 Vrms
3 V/m
d
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
