Recommended separation distances between portable and mobile RF communications equipment and the ME
EQUIPMENT or ME SYSTEM – for ME EQUIPMENT and ME SYSTEMS that are not LIFE-SUPPORTING
EMC Guidance
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 (transmittters) 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
Note 2
At 80MHz and 800MHz, the separation distance for the higher frequency range applies.
These guidelines may not apply in all situations. Electromagnetic propagation is affected
by absorption and reflection from structures, objects and people.
