Advantech POC-624-02 Series User Manual page 37

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 consid-

ered. If the measured field strength in the location in which the POC-621-02 series device

is used exceeds the applicable RF compliance level above, the POC-621-02 series device

should be observed to verify normal operation. If abnormal performance is observed, addi-

tional measures may be necessary, such as reorienting or relocating the POC-621-02

series device.

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