Emissions RF
CISPR 11
Class A
The emissions characteristics of
Microflow-S
make it suitable for use
in industrial areas and hospitals (CISPR 11 class A).
If it is used in a residential
Microflow-S
might not offer adequate
protection to radio-frequency communication services.
The user might need to take mitigation measures, such as relocating or
re-orienting this equipment.

Portable and mobile RF communications equipment
should be used no closer to any part of the
Microflow-S
including cables, than the
recommended separation distance of 30cm or 12
inches.
Note 1: 80 MHz to 2.7GHz, the higher frequency range applies.
Note2 : These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects, and people.
a Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless)
telephones and land mobile 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
Microflow-S
is used exceeds the applicable RF compliance level
above, the
Microflow-S
should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as re-orienting or relocating the
Microflow-S
.
Over the frequency range 150 kHz to 80MHz, field strengths should be less than 3 V/m
