Interference
immunity tests
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 60X7' exceeds the compliance level specified
above, the product 'BionicLink 60X7' 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 60X7'

The product 'BionicLink 60X7' is designed for operation in an electromagnetic environment
where HF interference is monitored. The customer or user of the product 'BionicLink 60X7' can
help prevent electromagnetic interference by complying with the minimum distances between
wearable and mobile HF communication equipment (transmitters) and the product 'BionicLink
60X7', as below according to the maximum output of the communication equipment.
