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

of the ADview, including cables, than the

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 ADview device is used exceeds the applicable RF compliance level above, the
ADview device should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-
orienting or relocating the ADview device.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
