Interference
immunity tests
Radiated HF interfer­
ence according to
IEC 61000-4-3
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.

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 'BionicLink 60X3' exceeds the compliance level specified
above, the product 'BionicLink 60X3' 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 'BionicLink 60X3'
IEC 60601 test level

a lesser distance from
the product 'Bion­
icLink 60X3' including
the lines than the
recommended safety
distance calculated
using the equation
applicable for the
transmission fre­
quency.
Recommended
safety distance:
d = 0.3 √P for 80 KHz
to 800 MHz
d = 2.3 √P for
800 MHz to 2.5 GHz
Where P is the nomin­
al output of the trans­
mitter in watts (W)
according to the trans­
mitter manufacturer
and d is the recom­
mended safety dis­
tance in metres (m).
The field strength of
stationary radio trans­
mitters at all frequen­
cies according to an
a
on-site investigation
should be less than
the compliance level.
Interference is pos­
sible in the vicinity of
devices that bear the
