STM 330 / STM 331 / STM 330C / STM 332U / STM 333U

5 AGENCY CERTIFICATIONS

The modules have been tested to fulfil the approval requirements for CE (STM 330 / STM

331) and FCC/IC (STM 330C / STM 332U / STM 333U) 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!

5.1 CE Approval

The STM 330 / STM 331 module bears the EC conformity marking CE and conforms to the

R&TTE EU-directive on radio equipment. The assembly conforms to the European and na-

tional requirements of electromagnetic compatibility. The conformity has been proven and

the according documentation has been deposited at EnOcean. The modules can be operated

without notification and free of charge in the area of the European Union and in Switzer-

land.

 EnOcean RF modules must not be modified or used outside their specifica-

tion limits.

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

Analog speech and/or music are not permitted.

 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 R&TTE Directive 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 33x 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).
