Recommended separation distances
between portable and mobile RF communications equipment and the Eclipse 3
The Eclipse 3 is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The cus-
tomer or the user of the Eclipse 3 can help prevent electromagnetic interference by maintaining a minimum distance between
portable and mobile RF communications equipment (transmitters) and the Eclipse 3 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.
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.
