Guidance and manufacturer’s declaration – electromagnetic immunity
The EEG32U is intended for use in the electromagnetic environment specified below. The customer or the user
of the EEG32U should assure that it is used in such an environment

Portable and mobile RF communications
equipment should be used no closer to any
part of the EEG32U, including cables, than
the recommended separation distance
calculated from the equation applicable to the
frequency of the transmitter.
Recommended separation distance
d=1.2 ×√P 150kHz to 80MHz
d=1.2 ×√P 80MHz to 800MHz
d=2.3 ×√P 800MHz to 2.5GHz
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

should be less than the compliance level in
each frequency

.
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.

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 EEG32U is used exceeds the applicable RF compliance level above, the EEG32U should
be observed to verify normal operation. If abnormal operation is observed, additional measures may be necessary, such as re-
orienting or relocating the EEG32U.

Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
