a Fixed transmitter manufacturers, such as: base stations for wireless (cellular / cordless) phones and ground mobile
radios, amateur radio, AM (Amplitude Modulation) and FM (Frequency Modulation) radio broadcasts, and
television broadcasts. The field strength is theoretically It is impossible to predict accurately. In order to evaluate the
electromagnetic environment of fixed RF transmitters, the survey of electromagnetic sites should be considered. If
the measured field strength of the infrared forehead thermometer is higher than the RF compliance level of the above
application, the infrared forehead thermometer should be observed to verify its normal operation. If abnormal
performance is observed, supplementary measures may be necessary, such as reorienting or positioning the infrared
thermometer.
b In the entire frequency range of 150KHz-80MHz, the plant strength should be lower than 3V / m.
