Guidance and manufacturer’s declaration-electromagnetic immunity
The Flex-MT® Plus is intended for use in the electromagnetic environment specified below.
The user of the Flex-MT® Plus should assure that it is used in such an environment.

Portable and mobile RF communications equipment should
be used no closer to any part of the
Flex-MT® Plus
including cables, than the recommended separation distance
calculated from the equation applicable to the frequency of
the transmitter.
Recommended separation distance:
d = 1.2 √P
d = 1.2 √P 80MHz to 800 MHz
d = 2.3 √P 800MHz to 2.5 GHz
Where P is the maximum output power rating of the
transmitter in watts (W) according to the transmitter
manufacturer and d is the recommended separation distance
in metres (m).
Field strengths from fixed RF transmitters, as determined by
an electromagnetic site survey,
a
should be less than the
compliance level in each frequency range.
b
Interference may occur in the vicinity of
equipment marked with the following symbol:
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 from 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 Flex-MT® Plus is used
exceeds the applicable RF compliance level above, the Flex-MT® Plus should
be observed to verify normal operation. If abnormal performance is
observed, additional measures my be necessary, such as re-orienting or
relocating the Flex-MT® Plus .
(b)
Over the frequency range 150 kHz to 80 MHz, field strengths should be
les than 3 V/m.
