To the FCC or FCC TCB handling this application Hereby w e, Company (grantee) FN-LINK TECHNOLOGY LIMITED FCC Modular Approval Request Addresss No.8, Litong Road, Liuyang Economic & Technical Development Zone, Changsha, Hunan, CHINA City / ZIP / State / Country China request m odular approval for the certification of our equipment w ithin this application, identified by:

FCC ID:

2AATL-6252B-UUB The table below contains justification for modular approval of this equipment. Requirement per DA 00-1407 1. The modular transmitter must have its ow n RF shielding. 2.The modular transmitter must have buffered modulation/data inputs (if such inputs are provided) to ensure that the module w ill comply w ith Part 15 requirements under conditions of excessive data rates or over-modulation. 3. The modular transmitter must have its ow n pow er supply regulation. 4.The modular transmitter must comply w ith the antenna requirements of Section 15.203 and 15.204(c). The antenna must either be permanently attached or employ a unique antenna coupler (at all connections betw een 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 w ith Part 15 emission limits regardless of the device into w hich it is eventually installed. 6. The modular transmitter must be labeled w ith its ow n FCC ID number, and, if the FCC ID is not visible w hen the module is installed inside another device, then the outside of the device into w hich the module is installed must also display a label referring to the enclosed module. This exterior label can use w ording such as the follow ing: Contains Transmitter Module FCC ID: ?????????? or Contains FCC ID: 2ATCG-BB810QI4A Any similar w ording that expresses the same meaning may be used. The Grantee may either provide such a label, an example of w hich must be included in the application for equipment authorization, or, must provide adequate instructions along w ith the module w hich explain this requirement. In the latter case, a copy of these instructions must be included in the application for equipment authorization. 7. The modular transmitter must comply w ith any specific rule or operating requirements applicable to the transmitter and the manufacturer must provide adequate instructions along w ith 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 w hich case there are separate field strength level and timing requirements. Compliance w ith these requirements must be assured. 8. The modular transmitter must comply w ith 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 millimetre w ave 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 w ith Section 15.247(b)(4). Modular transmitters approved under other Sections of Part 15, w hen 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.
