(Stepcode DE and later)

 

 

EnOcean. The modules can be operated without notification and free of charge in the area 
of the European Union and in Switzerland. 
 

 

 

EnOcean RF modules must not be modified or used outside their specifica-
tion limits. 
 

 

RED approval is only valid for delivered standard hardware and software 
 

 

EnOcean RF modules must not be used with gain antennas, since this may 
result in allowed ERP or spurious emission levels being exceeded. 
 

 

The final product incorporating EnOcean RF modules must itself meet the 
essential requirement of the EU directives and a CE marking must be af-
fixed on the final product and on the sales packaging each. Operating in-
structions containing a Declaration of Conformity has to be attached. 
 

 

If the STM 32x transmitter is used according to the regulations of the 868.3 
MHz band, a so-called “Duty Cycle” of 1% per hour must not be exceeded. 
Permanent transmitters such as radio earphones are not allowed. 
 

 

The module must be used with only the following approved antenna(s).
