Electromagnetic environment - guidance
Portable and mobile RF communications
equipment should be used no closer to any
part of the medinSINDI
®
, including cables,
than
the
recommended
separation
distance calculated from the equation
applicable to the frequency of the
transmitter.
Recommended separation distance:
Conducted RF
IEC 61000-4-6
3 V
rms
150 kHz
to
80 MHz
3 V
rms
𝑑 = 1.2√𝑃
Radiated RF IEC
61000-4-3
3 V/m
80 MHz to 2.5 GHz
3 V/m
𝑑 = 1.2√𝑃
80 MHz to 800 MHz
𝑑 = 2.3√𝑃
800 MHz 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 is to be
recommended. If the measured field strength in the location in which the medinSINDI
®
is used
exceeds the applicable RF compliance level above, the medinSINDI
®
must be observed to verify
normal operation. If abnormal performance is observed, additional measures may be
necessary, such as re-orienting or relocating the medinSINDI
®
.
b
Over the frequency range 150 kHz - 80 MHz field strengths should be less than 3 V/m.
