The field strength of stationary transmitters such as base stations of radio telephones and
mobile land radio equipment, amateur radio stations, AM and FM radio and television stations
cannot be precisely determined theoretically in advance. A site survey is recommended to estab
lish the electromagnetic conditions as a result of stationary HF transmitters. If the field strength
determined at the site of the product 'Genium X3 - Bionic Prosthetic System 3B5-X3 / Genium
X3 3B5-2' exceeds the compliance level specified above, the product 'Genium X3 - Bionic Pros
thetic System 3B5-X3 / Genium X3 3B5-2' has to be monitored in regards to normal operation at
each place of use. If unusual performance characteristics are noted, taking additional steps may
be necessary, for example changing the orientation or moving the product 'Genium X3 - Bionic
Prosthetic System 3B5-X3 / Genium X3 3B5-2'
Table 6 – Recommended safe distances between portable and mobile HF telecommunica
tion equipment and the product 'Genium X3 - Bionic Prosthetic System 3B5-X3 / Genium

The product 'Genium X3 - Bionic Prosthetic System 3B5-X3 / Genium X3 3B5-2' is designed for
operation in an electromagnetic environment where HF interference is monitored. The customer
or user of the product 'Genium X3 - Bionic Prosthetic System 3B5-X3 / Genium X3 3B5-2' can
help prevent electromagnetic interference by complying with the minimum distances between
wearable and mobile HF communication equipment (transmitters) and the product 'Genium X3 -
Bionic Prosthetic System 3B5-X3 / Genium X3 3B5-2', as below according to the maximum out
put of the communication equipment.

For transmitters with no maximum nominal output specified in the table above, the recommen
ded safety distance d in metres (m) can be determined using the equation in the respective
column, where P stands for the maximum nominal output of the transmitter in watts (W) accord
ing to the transmitter manufacturer's information.
Note 1:
The higher frequency range applies at 80 MHz and 800 MHz.
Note 2:
These directives may not be applicable in all cases. The propagation of electromagnetic
factors is influenced by absorption and reflection by buildings, objects and people.
