IEC 60601-1-2 Table 204
Guidance and manufacturer’s declaration – electromagnetic immunity
MH01 is intended for use in the electromagnetic environment specified below. The customer or
the end user of MH01 should assure that it is used in such an environment.
Electromagnetic environment - guidance
Portable and mobile RF communication
part of MH01, including cables, than the
recommended separation distance calculated
from the equation applicable to the frequency
of the transmitter.
Recommended separation distance.
d=1,167*sqrt (P)
d=1,167*sqrt (P) 80 MHz to 800 MHz
d=2,333*sqrt(P) 800 MHz to 2,5 GHz
Where P is the maximum output power rating
the transmitter in watts(W) according to
the transmitter manufacturer and d is the
recommended separation distance in metres
Field strengths from fixed RF transmitters, as
determined by an electromagnetic site survey
a
, should be less than the complian
each frequency range.
b
Interference may occur in the vicinity of
equipment marked with the following symbol:
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 strength 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 asses 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 MH01 is used exceeds the
applicable RF compliance level above, MH01 should be observed to verify normal operation.
If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating
MH01
b) Over the frequency range 150 KHz to 80 MHz, field strength should be less than 3 V/m.
