guidelines
Portable and mobile radio devices should
not be used in closer proximity to the
[device or system] including the cables as
the recommended protective distance
calculated in accordance with the formula
for the respective transmission frequency.
Recommended protective distance:
Conducted HF
disturbances
according to
IEC 61000-4-6
3 Vrms
150 kHz to 80
Mhz
3 Vrms
d = 1.2
Radiated HF
disturbances
according to
IEC 61000-4-3
3 V/m
80 MHz to 2.5
Ghz
3 V/m
d = 1.2 80 MHz to 800 MHz
d = 2.3 800 MHz to 2.5 GHz
Where P is the rated power of the
transmitter in watt (W) according to the
specification of the transmitter
manufacturer and d is the recommended
protective distance in metres (m).
According to an on-site
a
investigation, the
field strength of stationary radio
transmitters is in all frequencies lower than
the conformity level.
b
Disturbances are possible in the vicinity of
devices carrying the following symbol.
NOTE 1 For 80 MHz and 800 MHz, the higher value is applicable.
NOTE 2 These guidelines might not apply to all situations. The spreading of electromagnetic
waves is influenced by absorptions and reflections of buildings, objects and people.
