Recommended separation distance: 80 MHz to 800 MHz 800 MHz to 2.5 GHz Where P is the maximum output power rating of the transmitter in watts(W) according to the transmitter manufacturer and d is the recommended separation distance in meters(M). Field strengths from fixed RF transmitters as determined by an electromagnetic site survey, should be less than the compliance level in each frequency range. Interference may occur in the vicinity of equipment marked with the following symbol: NOTE •• At 80 MHz and 800 MHz, the higher frequency range applies. •• These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects and people. 1 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 considered. If the measured field strength in the location in which the EUT is used exceeds the applicable RF compliance level above, the EUT should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating the EUT. 2 Over the frequency range 150 kHz to 80 MHz, field strengths should be less than [V1] V/m. 7 Recommended separation distance between portable and mobile RF communications equipment and the EUT Separation distance according to frequency of transmitter [m] IEC 60601-1-2 Frequency of Transmitter 150 kHz to 80 MHz 80 MHz to 800 MHz 800 MHz to 2.5 GHz V1=3 Vrms E1=3 V/m E1=3 V/m Separation Distance (meters) Separation Distance (meters) Separation Distance (meters) 0.116 0.368 1.166 3.687 11.660 0.1166 0.3687 1.1660 3.6872 11.6600 0.2333 0.7378 2.3333 7.3785 23.333 Equation Rated maximum output power of transmitter [W] 0.01 0.1 1 10 100 For transmitters rated at a maximum output power not listed above, the recommended separation distance d in meters (m) can be estimated using the equation applicable to the frequency of the transmitter, where p is the maximum output power rating of the transmitter in watts (W) according to the transmitter manufacturer.
