Recommended separation

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 deter-mined by an
electromagnetic site survey,
(a) Should be less than the
compliance level in each
frequency range (b).
Interference may occur in the
vicinity of equipment marked with
the following symbol:
Note 1) Uт is the A.C. mains voltage prior to 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.
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 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.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than [V1] V / m.
