NOTE 1: U is the a.c. mains voltage prior to the application of the test level
T
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 affected 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 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 device is used exceeds the applicable RF compliance level above, the device should be
observed to verify normal operation. If abnormal performance is observed, additional measures may
be necessary, such as reorienting or relocating the device.
b) Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 10 V/m.

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 ranged.
