Limited module procedures N/A Trace antenna designs N/A RF exposure considerations This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. Antennas The module has one PCB antenna and the antenna gain is -0.58 dBi. Label and compliance information When the module is installed in the host device, the FCC ID label must be visible through a window on the final device or it must be visible when an access panel, door or cover is easily re-moved.
(enclosure). This investigation is especially important when integrating multiple modular transmitters where the certification is based on testing each of them in a stand-alone configuration. It is important to note that host product manufacturers should not assume that because the modular transmitter is certified that they do not have any responsibility for final product compliance. c) If the investigation indicates a compliance concern the host product manufacturer is obligated to mitigate the issue.
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.
