Guidance and Manufacturer's Declaration - Electromagnetic Immunity
The Guardian 2 Link is intended for use in the electromagnetic environment specified
below. The customer or user of the Guardian 2 Link should assure that it is used in
such an electromagnetic environment.
Immunity Test
Radiated RF
IEC 61000-4-3
Note:
At 80 MHz and 800 MHz, the higher frequency range applies.
Note:
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 broadcasts and TV broadcast cannot be pre-
dicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF trans-
mitters, an electromagnetic site survey should be considered. If the measured field strength in the
location in which the Guardian 2 Link is used exceeds the applicable RF compliance level above, the
Guardian 2 Link should be observed to verify normal operation. If abnormal performance is observed,
additional measures may be necessary, such as re-orienting or relocating the Guardian 2 Link.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
