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.

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.

Compliance Level Electromagnetic Environment - Guidance
Floors should be wood, concrete or ceramic tile. If
±6kV contact
floors are synthetic, the relative humidity should be at
±8kV air
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 of this
5 Cycles

Compliance Level Electromagnetic Environment - Guidance
Power frequency magnetic fields should be that of a
3A/m 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/
V1 = 3 Vrms
listed below:
D=(3.5/V1)√ P
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.
