The manual for the OEM integrators must include some instructions to be followed by the end users in the user manual. For example: The OEM integrators must be instructed to ensure that the end user has no manual instructions to remove or install the device. The OEM integrators must be instructed about the end product labeling ("Contains FCC ID:QDWWM168GC ") This device is intended only for OEM integrators under the following conditions: 1) The antenna must be installed such that 20 cm is maintained between the antenna and users, and 2) The transmitter module may not be co-located with any other transmitter or antenna. As long as the 2 conditions above are met, further transmitter test will not be required. However, the OEM integrator is still responsible for testing their end product for any additional compliance requirements required with this module installed (for example, digital device emissions, PC peripheral requirements, etc.). IMPORTANT NOTE: In the event that these conditions cannot be met (for example certain laptop configurations or co-location with another transmitter), then the FCC authorization is no longer considered valid and the FCC ID can not be used on the final product. In these circumstances, the OEM integrator will be responsible for re-evaluating the end product (including the transmitter) and obtaining a separate FCC authorization. End Product Labeling This transmitter module is authorized only for use in device where the antenna may be installed such that 20 cm may be maintained between the antenna and users (for example, access points, routers, wireless ADSL modems, wireless media adapter, wireless media gateway, and similar equipment). The final end product must be labeled in a visible area with the following: " Contains FCC ID:QDWWM168GC ". Manual Information for OEM integrator Following RF exposure info shall be supplied in end-users manual depends on the application. For mobile configuration of RF Exposure Information: IMPORTANT NOTE: To comply with FCC RF exposure compliance requirements, this grant is applicable to only Mobile Configurations. The antennas used for this transmitter must be installed to provide a separation distance of at least 20 cm from all persons and must not be co-located or operating in conjunction with any other antenna or transmitter

Please explain how this device can be installed to the equipments mentioned on the modular request letter. Ans #1: The external USB connector is test kit for this module.(will not be included for sale) Question#2: FCC DOC logo is not applied to this application. Please remove it. Ans #2: Please refer to the attached for the revised label fomat. Question#3: Based on the modular request letter, this device is required to be installed by OEM manufacturer. However, in the submitted user manual, the manual is written in such way to allow the end user to install this product which does not agree with OEM installation instruction and marketing to OEM only. Please provide revised the user manual in such way that the user manual is addressed to OEM . Ans #3: The user's manual has been modify. Please refer to the attached. Question#4: Based on the test report and EUT external photos, a PIFA antenna is used for this device but the one indicated on the last page of user manual which indicates Chip antenna . Please explain. Ans #4: The user's manual has been modify. Please refer to the attached. Question#5: Page 3 of test report, the signature page, no signature included. Per ANSI C63.4 section 10.11.1, test report shall contain the signature of the representative of the organization performing the tests. Please provide. Ans #5: Page 3 of test report has been modify. Please refer to the attached. Question#6: Based on the EUT external photos, this device has two antenna connectors with a PIFA antenna. Please indicate which antenna connector was measured during test and how the other antenna connector will be used. Ans #6: This device will has one antenna connector with a PIFA antenna. Another antenna connector that will not using for Rx diversity by the software, so needless to SMT process for this component on the module.
