Note 1) During the 5 Second event, the enFlow 100 and 120 power off, but return to normal operation as soon as
power is restored.
Guidance and Manufacturer's Declaration – Emissions
The enFlow 100 with enFlow 120 is intended for use in the electromagnetic environment
specified below. The customer or user of the enFlow 100 with enFlow 120 should ensure that
it is used in such an environment.

Recommended Separation Distances Between Portable and Mobile RF Communications
Equipment and the enFlow
The enFlow 100 with enFlow 120 is intended for use in the electromagnetic environment in which radiated
disturbances are controlled. The customer or user of the enFlow 100 with enFlow 120 can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile RF Communications
Equipment and the enFlow 100 with enFlow 120 as recommended below, according to the maximum output power
of the communications equipment.

interruptions, it is recommended that
the enFlow 100 with enFlow 120 be
powered from an uninterruptible
power supply or battery.
Power frequency magnetic fields
should be that of a typical commercial
or hospital environment.
Electromagnetic Environment – Guidance
Portable and mobile communications
equipment should be separated from
the enFlow 100 with enFlow 120 by no
less than the distances calculated/listed
below:
D=(3.5/3V/m)(Sqrt P)
D=(3.5/3V/m)(Sqrt P)
80 to 800 MHz
D=(7/3V/m)(Sqrt P)
800 MHz to 2.5 GHz
where P is the max power 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 (3Vrms and 3V/m).
Interference may occur in the vicinity of
equipment containing a transmitter.
