NOTE: 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.
(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.
