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
NOTE 4: The performance of wireless functions in the presence of Electromagnetic Interference has
not been evaluated.
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.

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).
b
Field strengths from fixed RF
transmitters, as determined by
an electromagnetic site
survey , should be less than the
compliance level in each
frequency ranged.
Interference may occur in the
vicinity of equipment marked
