DM DOC 040 Rev 1.0
Guidance and manufacturer’s declaration – electromagnetic immunity
D-MAS is intended for use in the electromagnetic environment specified below. The customers
or the users of the D-MAS should assure that it is used in such environment.
Immunity test
IEC 60601
Test level
Compliance level Electromagnetic environment – guidance
Conducted RF
IEC 61000-4-6
Radiated RF
IEC 61000-4-3
3 V rms
150 kHz ~ 80
MHz
3 V/m
80 MHz to
2.5 GHz
3 V rms
3 V/m
Portable and mobile RF communications
equipment should be used no closer to any
part of the D-MAS including cables, than
the recommended separation distance
calculated from the equation appropriate to
the frequency of the transmitter.
Recommend separation distance
80 MHz to 800 MHz
800 MHz to 2.5 GHz
where
P
is the maximum output power
rating of the transmitter in watts (W) and
d
is the recommended separation distance in
meters (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:
Note1: At 80 MHz and 800 MHz, the higher frequency range applies.
Note2: 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 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 D-MAS is used exceeds the applicable RF compliance level
above, the D-MAS should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as reorienting or relocating the D-MAS.
b) Over the frequency range 150 kHz to 80MHz, field strengths should be less than 3 V/m.
