Guidance and manufacturer’s declaration – electromagnetic immunity

The MR810 is intended for use in the electromagnetic environment specified below. The customer or the user of the MR810 should assure that it is used in such an environment

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 poles

aField 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 MR810 is used exceeds the applicable RF compliance level above, the MR810 should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the MR810.

bOver the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
