Guidance and manufacturer’s declaration – electromagnetic immunity
The MR810 is intended for use in the electromag n etic environment specified below. The customer or the user
of the MR810 should assure that it is used in such an environment

recommended separation distance calculated
from the equation applicable to the frequency
of the transmitter.
Recommended separation distance
d = 1,2√P
d = 1,2√P 80 MHz to 800 MHz
d = 2,3√P 800 MHz to 2,5 GHz
where P is the maximum output power rating
of the transmitter in watts (W) according to
the transmitter manufacturer and d is the
recommended separati o n distance in metres
(m).

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 poles
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 MR810 is used exceeds the applicable RF compliance level above, the MR810 should be observed to
verify normal operation. If abnormal performance is observed, additional measures may be necessary,
such as reorienting or relo cating the MR810.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
