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.

Compliance Level Electromagnetic Environment - Guidance
Floors should be wood, concrete or ceramic
±6kV contact
tile. If floors are synthetic, the relative humidity
±8kV air
should be at least 30%.
Mains power quality should be that of a typical
±2kV on AC Mains
commercial or hospital environment.
±1kV Differential Mains power quality should be that of a typical
±2kV Common commercial or hospital environment.
>95% Dip for
0.5 Cycle
Mains power quality should be that of a typical
60% Dip for
commercial or hospital environment. If the user
5 Cycles
of this device requires continued operation
during power mains interruptions, it is
30% Dip for
recommended that the device be powered from
25 Cycles
an uninterruptible power supply or battery.

Compliance Level Electromagnetic Environment - Guidance
Power frequency magnetic fields should be that
3A/m 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
V1 = 3 Vrms
distances calculated/listed below:
D=(3.5/V1)
D=(3.5/E1)√ P
D=(7/E1)√ P
Where P is the maximum power rating in watts
and D is the recommended separation distance
in meters.
E1 = 3V/m
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.
