Guidance and manufacturer’s declaration – electromagnetic immunity
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
THixyz series is used exceeds the applicable RF compliance level above, the
THixyz series should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as reorienting or relocating the
THixyz series.
b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
Guidance and manufacturer’s declaration – electromagnetic immunity
The THixyz series is intended for use in the electromagnetic environment specified
below. The customer or the user of the THixyz series should assure that it is used in
such an environment.
