– electromagnetic immunity – WP200
The
WP 200
is intended for use in the electromagnetic environment specified below; The customer or the user of the
WP200
should assure that it is used in such an environment.

Field strengths from fixed R F transmitters, as
determined by an electromagnetic site survey ,
a
should be
less than the compliance level in each frequency
range .
d
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
WP200
is used exceeds the applicable RF compliance level above, the
WP200
should be
observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-
orienting or relocating the
WP200
.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
