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:
P = maximum output power rating of the
transmitter in watts (W) according to the
transmitter manufacturer and d = the
recommended separation distance in meters (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/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.
b
Over the frequency range 150 kHz to 80 MHz, the field strengths should be less than 3 V/m.
