Note *: UT is the AC mains voltage prior to application of the test level.
Note 1: At 80 MHz and 800 MHz, the higher frequency range applies.
Note 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection of structures,
objects, and people.
a) Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radio,
AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due
to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the FLU-
ENT FLUID MANAGEMENT SYSTEM is used exceeds the applicable compliance level above, the FLUENT FLUID MANAGEMENT SYSTEM should
be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or
relocating the changing orientation or the location of the FLUENT FLUID MANAGEMENT SYSTEM.
b) Over the frequency range of 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

Recommended Separation Distances

The following lists the recommended separation distances between portable and mobile RF communications equipment and the FLUENT FLUID
MANAGEMENT SYSTEM.
Recommended Separation Distances
The FLUENT FLUID MANAGEMENT SYSTEM is intended for use in an electromagnetic environment in which radiated RF disturbances are con-
trolled. The customer or the user of the FLUENT FLUID MANAGEMENT SYSTEM can help prevent electromagnetic interference by maintaining a
minimum distance between portable and mobile RF communications equipment (transmitters) and the FLUENT FLUID MANAGEMENT SYSTEM as
recommended below, according to maximum output power of the communications equipment.

Portable and mobile RF communications
equipment used no closer to any part of the
FLUENT FLUID MANAGEMENT SYSTEM, including
cables, than the recommended separation
distance calculated from the equation applicable
to the frequency of the transmitter.
Recommended safety distance:
d = 1.2√P for 150 KHz to 80 MHz
d = 1.2√P for 80 MHz to 800 MHz
d = 2.3√P for 800 MHz to 2.7 GHz
Where P as the maximum output power rating
of the transmitter in watts [W] according to the
transmitter manufacturer d as recommended
separation distance in meters [m].
Field strengths from fixed RF transmitters, as
determined by an electromagnetic site survey
should be less than the compliance level in each
frequency range.
