Radiated RF
IEC 61000-4-3
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 separation distance for the higher frequency range applies.
Note 2: T hese guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects, and people.
Recommended Separation Distances Between Portable and Mobile RF Communications Equipment and
this device. This device and system are NOT Life-Supporting
This device is intended for use in the electromagnetic environment in which radiated disturbances are controlled. The customer or user of this device can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile RF Communications Equipment and the device as recommended below,
according to the maximum output power of the communications equipment.

Electromagnetic Environment - Guidance
Power frequency magnetic fields should be that of a typical location in a typical
commercial or hospital environment.
Portable and mobile RF communications equipment should be separated from the
device by no less than the recommended separation distances calculated/listed
below:
D=(3.5/V1)
√ P
D=(3.5/E1)√ P 80 to 800 MHz
800 MHz to 2.5 GHz
D=(7/E1)√ P
Where P is the maximum power rating in watts and D is the recommended
separation distance in meters.
Field strengths from fixed transmitters, as determined by an electromagnetic site
survey, should be less than the compliance levels (V1 and E1).
Interference may occur in the vicinity of equipment containing a transmitter.
