Guidance and manufacturer´s declaration – electromagnetic immunity
The Eva400EM/EE is intended for use in the electromagnetic environment specified below. The customer
or the user of the Eva400EM/EE should assure that it is used in such an environment.

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:
NOTE 1 At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic 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
Eva400EM/EE
is used exceeds the applicable RF compliance level above, the
Eva400EM/EE
should be
observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or
relocating the
Eva400EM/EE
.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
