DR 18M, DR 24M | Remarks for HF-emission and immunity | 77
Note: The higher value will apply at 80 MHz and 800 MHz.
Note: These Guidelines may not apply to all situations. The
dispersion of electromagnetic waves is influenced by absorption
and reflections from buildings, objects and people.
Note: The field strength of stationary transmitters, such as
base stations of radio telephones, mobile broadcasts for rural
areas, amateur stations, and AM and FM radio transmitters,
cannot be precisely predetermined theoretically. An
investigation of the location is recommended, to ascertain
the electromagnetic environment as a result of stationary
high frequency transmitters. If the field strength of the
device exceeds the level of agreement given above, the
d = 2.3
800 MHz to
2.5 GHz
With P as the rated power
of the transmitter in
watts (W) in accordance
with the manufacturer
information on the
transmitter and d as the
recommended protective
distance in metres (m).
The field strength of
stationary radio
transmitters is lower than
the level of the
agreement at all
frequencies in
accordance with an on-
site investigation.
Disruptions are possible
near devices that carry
the following symbol:
0380A EN 20180703 1429
