Recommended separation distances between
portable and mobile RF communications equipment and the
ERO•SCAN
®
.
The
ERO
•
SCAN
®
is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The
customer or the user of the
ERO
•
SCAN
®
can help prevent electromagnetic interferences by maintaining a minimum distance
between portable and mobile RF communications equipment (transmitters) and the
ERO
•
SCAN
®
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
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 higher frequency range applies.
Note 2
These guidelines may not apply to all situations. Electromagnetic propagation is affected by absorption and reflection from
structures, objects and people.
