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, ob-
jects and people.
a Field strengths from fixed transmitters, such as base stations for
radio (cellular/cordless) telephones and land mobile radios, amateur ra-
dio, 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 con-
sidered. 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.
Recommended separation distances between portable and mobile
Portable and mobile RF communications
equipment should be used no closer to
any part of the device, including cables,
than the recommended separation dis-
tance calculated from the equation ap-
plicable to the frequency of the transmit-
ter.

Where P is the maximum output power

cording to the transmitter manufacturer
and d is the recommended separation
distance in metres (m).
Field strengths from fixed RF transmit-
ters, as determined by an electromag-
netic site survey, a should be less than
