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: These 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:
√ P
D=(1.2)
D=(1.2)√ P 80 to 800 MHz
D=(2.3)√ P 800 MHz to 2.5 GHz
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 (3 Vrms and 3V/m).
Interference may occur in the vicinity of
equipment containing a transmitter.
