environment – guidance
Portable and mobile RF communications
equipment should be used no closer to
any part of the device, including cables,
than the recommended separation
distance calculated from the equation
applicable to the frequency of the
transmitter.
Recommended separation distance
Not Applicable3V rms
At 0.15-80 MHz
6V rms
At ISM & Radio
Amateur Freq.

d = 1.2
d = 1.2 80 MHz to 800 MHz
d = 2 .3 800 MHz to 2.5 GHz
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 metres (m).

transmitters, as determined by an
electromagnetic site survey,

NOTE 1 At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2 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.
