Page 36: Agency Certifications
The conformity has been proven and the ac- cording documentation has been deposited at EnOcean. The modules can be operated with- out notification and free of charge in the area of the European Union and in Switzerland. -
Page 37: Fcc (United States) Certification
United States without additional Part 15 FCC approval (ap- proval(s) for unintentional radiators may be required for the OEM’s finished product), under EnOcean’s FCC ID number. This greatly simplifies and shortens the design cycle and devel- opment costs for OEM integrators. - Page 38 STM 300 / STM 300C OEM Requirements In order to use EnOcean’s FCC ID number, the OEM must ensure that the following condi- tions are met. End users of products, which contain the module, must not have the ability to alter the firmware that governs the operation of the module.

Page 40: Ic (Industry Canada) Certification
STM 300 / STM 300C IC (Industry Canada) certification In order to use EnOcean’s IC number, the OEM must ensure that the following conditions are met: Labeling requirements for Industry Canada are similar to those required by the FCC. The Original Equipment Manufacturer (OEM) must ensure that IC labeling requirements are met.
