Requesting modular approval The company Engineering and Security SRL request the limited modular approval of the BlueAudio2 device that has the follow characteristics: 1. The modular transmitter haven't its own RF shielding. 2. The modular transmitter has standard bluetooth V1.1 modulation/data rates. 3. The modular transmitter has its own power supply regulation. 4. The modular transmitter is comply with the antenna requirements of Section 15.203 and 15.204(c). The antenna is permanently attached. 5. The modular transmitter is tested in a stand-alone configuration, i.e., the module is not inside another device during testing. 6. The modular transmitter is labeled with its own FCC ID number, and, if the FCC ID is not visible when the module is installed inside another device, then the outside of the device into which the module is installed must also display a label referring to the enclosed module. 7. The modular transmitter is comply with any specific rule or operating requirements applicable to the transmitter and the manufacturer must provide adequate instructions along with the module to explain any such requirements. A copy of these instructions must be included in the application for equipment authorization. 8. The modular transmitter is comply with any applicable RF exposure requirements. For example, FCC Rules in Sections 2.1091, 2.1093 and specific Sections of Part 15, including 15.319(i), 15.407(f), 15.253(f) and 15.255(g), require that Unlicensed PCS, UNII and millimeter wave devices perform routine environmental evaluation for RF Exposure to demonstrate compliance. In addition, spread spectrum transmitters operating under Section 15.247 are required to address RF Exposure compliance in accordance with Section 15.247(b)(4). Modular transmitters approved under other Sections of Part 15, when necessary, may also need to address certain RF Exposure concerns, typically by providing specific installation and operating instructions for users, installers and other interested parties to ensure compliance. Yours Sincerely, Giancarlo Olive
