The distance between portable or mobile RF-communications
equipment and parts of the product, including cables, should not be
less than the recommended protective distance calculated with the
equation applicable to the transmission frequency.
Recommended protective distance:
d = 1,2√P
d = 1,2√P
for 80 MHz to 800MHz
d = 2,3√P
for 800 MHz to 2.7 GHz
Here P is the maximum nominal power output of the transmitter in
watts (W) according to the transmitter manufacturer‘s specifi cations,
and d is the recommended distance in metres (m).
The fi eld strength of permanently installed RF-transmitters, which
was determined by an electromagnetic location test a should not
exceed the level b permitted in any frequency range. Interference
may occur in the immediate vicinity of equipment marked with the
following symbol:
Note 1: At 80 MHz and 800 MHz respectively, the larger frequency range applies.
Note 2: These guidelines may not apply to all situations. The propagation of electromagnetic waves is aff ected by the absorption and refl ection of
structures, objects, people and animals.
a
The fi eld strength of permanently installed transmitters, such as base stations for radio telephony (cordless or mobile phones), mobile radio stations,
amateur radio transmitters, AM and FM radio and television transmitters, cannot theoretically be calculated with absolute accuracy. To determine the
electromagnetic fi elds generated by fi xed RF-transmitters, an electromagnetic site inspection should be carried out. If the measured fi eld strength at the
location where the device is used exceeds the permissible RF-fi eld strength specifi ed above, the instrument should be observed. Additional measures
may be necessary, e.g. reorientation or change of location of the device.
b In the frequency range between 150 kHz and 80 MHz, the fi eld strength should be less than 3 V/m.
