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
d = . P
d = . P 0 MHz to 00 MHz
d = . P 00 MHz to . GHz
where P is the maximum output power
rating of the transmitter in watts (W) ac-
cording to the transmitter manufacturer
and d is the recommended separation
distance in meters (m).
Field strengths from xed RF transmitters,
as determined by an electromagnetic site
survey
a
, should be less than the compli-
ance level in each frequency range.

Interference may occur in the vicinity of
equipment marked with the following
symbol:
NOTE : At 0 MHz and 00 MHz, the higher frequency range applies.
NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reection from structures, objects, and people.
a Field strengths from xed 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 xed RF
transmitters, an electromagnetic site survey should be considered. If the measured eld 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 0 kHz to 0 MHz, the eld strengths should be less than  V/m.
