Recommended Separation Distances
Refer to the following table for recommended separation distances between
the Atria and portable and mobile RF communications equipment.
The Atria is intended for use in an electromagnetic environment in which
radiated RF disturbances are controlled. The user of the Atria can help
prevent electromagnetic interference by maintaining a minimum distance
between portable and mobile RF communications equipment (transmitters)
and the Atria 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 metres (m) can be estimated 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.
NOTE1: 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.
