Electromagnetic environment guidance
Portable and mobile RF communication
equipment should be used no closer to any
part of the CS5+ system, 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
Radiated RF
IEC 61000-4-3
3 Vrms
150 kHz to
80 MHz
3 V/m
80 MHz to
2.5 GHz
V1 = 3 Vrms
E1 = 3 V/m
Where
P
is the maximum output rating of
the transmitter in watts (W) according to
the transmitter manufacturer and
d
is the
recommended separation distance in
meters.
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 vi-
cinity 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 broadcast and TV broadcast cannot be predicted theoretically with accuracy. To asses
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 CS5+ system is used exceeds the applicable RF compliance level
above, the CS5+ system should be observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as reorienting or relocating the CS5+ system.
b)
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than [V1]
V/m.
