The modules have been tested to fulfil the approval requirements for CE (TCM 3x0) and 

FCC/IC (TCM 3x0C) based on the built-in firmware. 
 

 

When developing customer specific firmware based on the API for this module, 
special care must be taken not to exceed the specified regulatory limits, e.g. the 

duty cycle limitations! 

 

The modules bear the EC conformity marking CE and conforms to the R&TTE EU-directive 
on radio equipment. The assembly conforms to the European and national requirements of 
electromagnetic compatibility. The conformity has been proven and the according docu-

mentation has been deposited at EnOcean. The modules can be operated without notifica-
tion and free of charge in the area of the European Union, and in Switzerland. The following 

provisos apply: 
 

•  EnOcean RF modules must not be modified or used outside their specification 

limits. 

•  EnOcean RF modules may only be used to transfer digital or digitized data.

on the final product and on the sales packaging each. Operating instructions 
containing a Declaration of Conformity has to be attached. 

•  If the 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.
