immunity – for EQUIPMENT and SYSTEM that are not LIFE-SUPPORTING (see
6.8.3.201 b))
Guidance and manufacturer’s declaration-electromagnetic immunity (T.204)
The EHY-2000plus device is intended for use in the electromagnetic environment specified below. The
customer or the user of the EHY-2000plus should assure that it is used in such environment.

Portable and mobile RF communications
equipment should be used no closer to any
part of the EHY-2000plus, 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
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 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 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 EHY-2000plus is used exceeds the applicable RF compliance level
above, the EHY-2000plus should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as reorienting or relocating the EHY-2000plus
device.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
