Power frequency magnetic fields should be that of a typical location in a typical
commercial or hospital environment.
Conducted RF IEC 61000-4-6
3 Vrms from
150 kHz to 80 MHz
V1 = 3 Vrms
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
Radiated RF IEC 61000-4-3
3 V/m
80 MHz to 2.5 GHz
E1 = 3V/m
D=(3.5/E1)√P 80 to 800 MHz
D=(7/E1)√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 (V1 and E1).
Interference may occur in the vicinity of equipment containing a transmitter.
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.
