RF_734_02 04 April 16 Modular Approval Request FCC (KDB 996369 D01 & Part 15.212) FCC ID: _ PPQ-WCBN3606L ___ Items to be covered by Single modular transmitters. 1. The modular transmitter must have its own RF shielding. 2. The modular transmitter must have buffered modulation/data inputs (if such inputs are provided) to ensure that the module will comply with Part 15 requirements under conditions of excessive data rates or over-modulation. 3. The modular transmitter must have its own power supply regulation. 4. The modular transmitter must comply with the antenna requirements of Section 15.203 and 15.204(b)(c). The antenna must either be permanently attached or employ a unique antenna coupler (at all connections between the module and the antenna, including the cable). Answer from applicant Yes, the modular transmitter has metal shielding. Yes, the modular transmitter uses MT7603U for buffered/

data inputs. Yes, the modular transmitter has its own power supply regulator. Yes, the antenna of the modular transmitter complies with FCC requirements. 5. The modular transmitter must be tested in a stand-alone configuration, i.e., the module must not be inside another device during testing. This is intended to demonstrate that the module is capable of complying with Part 15 emission limits regardless of the device into which it is eventually installed. Yes, the modular transmitter is tested in a stand-alone configuration. 6. The modular transmitter must be equipped with either a permanently affixed label or must be capable of electronically displaying its FCC identification number in accordance with 15.212 (a)(1)(vi)(A) / (B). 7. The modular transmitter must 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 there are very strict operational and timing authorization. For example, requirements that must be met before a transmitter is authorized for operation under Section 15.231. For instance, data transmission is prohibited, except for operation under Section 15.231(e), in which case there are separate field strength level and timing requirements. Compliance with these requirements must be assured. 8. 9. The modular transmitter must comply with any applicable RF exposure requirements. For example, FCC Rules in Sections 1.1310, 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. 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. Yes, when the module is installed inside another device, it will be labelled as contain transmitter module XXXXXXXXX Yes, the users manual has provide instructions to explain the requirements. Yes, the radiated output power is far below the FCC radio frequency exposure limits. Note: A limited modular approval (LMA) may be granted for single or split modular transmitters that comply partially with the requirements above.
