Recommended separation distances between RF wireless communications
equipment
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 RF wireless
communications equipment and the device as recommended below, according to the maximum
output power of the communications equipment.

RF wireless 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
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, should be less than
the compliance level in
each frequency range.
Interference may occur in
the vicinity of equipment
