equipment
should be used no closer to any part of the
product including cables, than the
recommended separation distance
calculated in accordance with the equation
applicable to the
frequency of the transmitter.
Recommended separation distance
d=0.35√P
d=1.2√P 80 MHz up to 800 MHz
d=2.3√P 800 MHz up to 2.5 GHz
With
P
as the rated output of the transmitter
in Watt (W) in accordance with the
manufacturer’s specifications and
d
as the
recommended separation distance in meter
(m).
The field strength of fixed HF-transmitters
as determined by an electromagnetic field
survey,
a
–
should be less than the COMPLIANCE
LEVEL in each frequency range.
b
In the vicinity of equipment marked with the
following
symbol, interference may occur:
NOTE 1:
At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2:
This manual could possibly not apply to all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects and people.
a
The field strength of fixed RF transmitters, such as base stations of mobile phones and land mobile radios,
amateur radio stations, AM and FM radios as well as radio and television broadcast media cannot be
predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF
transmitters, an electromagnetic site survey is recommended. If the field strength measured in the
environment where the product is to be used, exceeds the applicable HF compliance level, special care
should be taken that a normal operation of the product can be guaranteed. In case anomalies are identified,
additional measures could be required, such as a different alignment or a change of the location of the
product.
b
In the frequency range from 150 kHz to 80 MHz, the field strength must be less than 10 V/m.
