Interference may occur in the vicinity of
equipment marked with the following symbol:
a. Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land
mobile radios, amateur radios, 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 X12+ Transmitter is used exceeds
the applicable RF compliance level above, the X12+ Transmitter should be observed to verify normal operation. If
abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the
X12+ Transmitter.
b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than [3] V/m.
