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:
3 V
where P is the maximum output power rating
of the transmitter in watts (W) according
to the transmitter manufacturer and d is
3 V/m
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:
Recommended separation distances between portable and mobile RF
communications equipment and the device
The device is intended for use in an electromagnetic environment in which radiated RF disturbances
are controlled. The customer or the user of the device can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF communications equipment (transmitters)
and the device as recommended below, according to the maximum output power of the communications
equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation distance d
in meters (m) can be determined using the equation applicable to the frequency of the transmitter, where P is
the maximum output power rating of the transmitter in watts (W) according to the transmitter manufacturer.
NOTE 1 At 80 MHz and 800 MHz, the separation distance for 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.
