Lanto Electronic Ltd Modular Approval Request FCC (KDB 996369 D01 & Part 15.212) FCC ID: 2APYS-LPS-15WPB Items to be covered by Single modular transmitters. 1. The modular transmitter must have its own RF shielding. Answer from applicant No, The LPS-15WP B module

(FCC id 2APYS-LPS-

15WPB) will be installed only on the three host devices:

IdeaCentre AIO 5 24AC IdeaCentre AIO 5 24IOB and IdeaCentre AIO 5 27IOB. These modules and devices will be assembled fac-

tories by professional workers. Our customer didnt need to know how to installed the mod-

ules with the devices by themselves. We provided manuals to guide our customers to use the host device and to use wireless charge function for the host device. YES No, The module will be installed only on the two host devices:

Product: Personal Computer Model name: IdeaCentre AIO 5 24ALC6 , IdeaCentre AIO 5 24IOB6 and IdeaCentre AIO 5 27IOB6. Brand: Lenovo YES 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). 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 YES 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 authorization. For example, there are very strict operational and timing 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. 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 8. YES YES Lanto Electronic Ltd 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. Note: A limited modular approval (LMA) may be granted for single or split modular transmitters that comply partially with the requirements above.
