Guidance and manufacturer’s declaration-electromagnetic immunity (T.204)
The WEY-2000plus device is intended for use in the electromagnetic environment specified below.
The customer or the user of the WEY-2000plus should assure that it is used in such environment.
Electromagnetic environment - guidance
Conducted RF
IEC 61000-4-6
Radiated RF
IEC 61000-4-3
3Vrms
150kHz to
80MHz
3V/m
80MHz to
2.5GHz
Portable and mobile RF communications
equipment should be used no closer to any
part of the WEY-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 WEY-2000plus is used exceeds the applicable RF compliance
level above, the WEY2000plus should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as reorienting or relocating
the WEY-2000plus.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
