Where P is the maximum output

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 ,
a should be
less than the compliance level in each
frequency ranged.
Interference may occur in the vicinity
of equipment marked with the following
symbol:
NOTE 1
: U
T
is the a.c. mains voltage prior to the application of the test level
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
NOTE 4
: The ISM (industrial, scientific and medical) bands between 0.15 MHz and 80 MHz are 6.765 MHz to 6.795
MHz; 13.553 MHz to 13.567 MHz; 26.957 MHz to 27.283 MHz; and 40.66 MHz to 40.70 MHz. The amateur radio
bandsbetween 0.15 MHz and 80 MHz are 1.8 MHz to 2.0 MHz, 3.5 MHz to 4.0 MHz, 5.3 MHz to 5.4 MHz, 7 MHz to
7.3 MHz,10.1 MHz to 10.15 MHz, 14 MHz to 14.2 MHz, 18.07 MHz to 18.17 MHz, 21.0 MHz to 21.4 MHz, 24.89 MHz to
24.99MHz, 28.0 MHz to 29.7 MHz and 50.0 MHz to 54.0 MHz.
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.
