Portable and mobile RF communications
equipment should be used not 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
80 MHz to 800 MHz
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).
Field strengths from fixed RF
transmitters, as determined 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 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 cord-
less) 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
[Vi] V/m.
