Guidance and manufacturer’s declaration - electromagnetic immunity
The
EJ-MLA26
Series is intended for use in the electromagnetic environment specified below. The
customer or the user of the
EJ-MLA26
Series should assure that it is used in such an environment.

Electromagnetic environment - guidance
Portable and mobile RF communications
equipment should be used no closer to any part
of the
EJ-MLA26
Series, including cables, than
the recommended separation distance calculated
from the equation applicable to the frequency of
the transmitter.

where
P
is the maximum output power rating of
the transmitter in watts (W) according 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:
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, 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
EJ-MLA26
Series is used exceeds the applicable RF compliance level above,
the
EJ-MLA26
Series should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as re-orienting or relocating the
EJ-MLA26
Series.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
