- Page 10 (OEM) Integrator has to assure compliance of the entire end‐product incl. the integrated RF Module. Additional measurements (15B) and/or equipment authorizations (e.g Verification) may need to be addressed depending on co‐location or simultaenous transmission issues if applicable. Integrator is reminded to assure that these installation instructions will not be made available to the end‐user of the final host device. With the low output power, this RF Module meets the FCC SAR exemption and can be therefore integrated into any (portable, mobile, fixed) host device. The final host device, into which this RF Module is integrated" has to be labelled with an auxilliary lable stating the FCC ID of the RF Module, such as "Contains FCC ID: ". N8NLSD4WF Depending on the size of the final end‐product, the §15.19 FCC statement "This device complies with part 15 of the FCC rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation." ...
- Page 11 : This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications.
