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.
