NOTE 2: At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 3: These guidelines may not apply in all situations. Electromagnetic propagation is af-
fected by absorption and reflection from structures, objects and people
a)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 pre-
dicted 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 device is used exceeds the applicable RF compliance
level above, the device should be observed to verify normal operation. If abnormal perfor-
mance is observed, additional measures may be necessary, such as reorienting or relocat-
ing the device.
b) Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 10 V/m.
