Guidance and manufacturer's declaration – electromagnetic immunity
The EM 29 is intended for use in the electromagnetic environment specified below. The customer or the user of the EM 29 should
assure that it is used in such an environment.
IMMUNITY IEC 60601

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, ama-
teur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electro-
magnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field
strength in the location in which the EM 29 is used exceeds the applicable RF compliance level above, the EM 29 should be obser-
ved to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting
or relocating the EM 29.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
Compliance Electromagnetic environment – guidance
level
Portable and mobile RF communications equipment should be used no closer to any
part of the EM 29, including cables, than the recommended separation distance cal-
culated from the equation applicable to the frequency of the transmitter.
Recommended separation distance:
3V
d = 1,2 x P
1/2
d = 2,3 x P
1/2
3V
Where P is the maximum output power rating of the transmitter in watts (W) accor-
3 V/m
ding 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,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:
80 MHz to 800 MHz
800 MHz to 2,5 GHz
