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
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 meters (m).
Field strengths from fixed RF transmitter,
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 applied.
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 re-orienting or relocating the device.
b
Over the frequency range 150 kHz to 80 MHz, the field strengths should be less than 10
V/m.
