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.

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.

Over the frequency range 150 kHz to 80 MHz, field strengths should be less than [V1] V/m.

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.
