Guidance and manufacturer’s declaration-electromagnetic immunity

The ET2400LM is intended for use in the electromagnetic environment specified below. The user of the ET2400LM

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 situation. Electromagnetic propagation is affected by absorption and reflection from structures, objects and people.

3.Filed 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 filed strength in the location in which the ET2400LM is used exceeds the applicable RF compliance level above, the ET2400LM should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the ET2400LM.

4.Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 Vrms.
