Liou, The review of this application is complete. The following items are needed to complet e issue the grant. 1. The user manual states that the antenna can be either internal or external. The a details about the antenna tested. The approval will be issued only for antennas include revise the test report or provide a separate antenna specification with details about the please refer to item 7 below) 2. The modular approval letter needs additional information. Conditions for modula required content for the modular approval request letter are shown below. Please pr o approval letter to include information as applicable in items M1-M8 below. MODULAR APPROVAL LETTER INFORMATION ITEMS M1. The modular transmitter must have its own RF shielding. This is intended to e n does not have to rely upon the shielding provided by the device into which it is installe modular transmitter emissions to comply with Part 15 limits. It is also intended to preve the RF circuitry of the module and any wires or circuits in the device into which the mo coupling may result in non-compliant operation. M2. The modular transmitter must have its own power supply regulation. This is in t the module will comply with Part 15 requirements regardless of the design of the powe the device into which the module is installed. Any antenna used with the module must module, either at the time of initial authorization or through a Class II permissive chang calculation for licensed modules must account not just for compliance with MPE but al ERP/EIRP limits. M3. The modular transmitter must be tested in a stand-alone configuration, i.e., the inside another device during testing. This is intended to demonstrate that the module with Part 15 emission limits regardless of the device into which it is eventually installe d transmitter module will be battery powered, it must comply with the AC line conducted Section 15.207. AC or DC power lines and data input/output lines connected to the m ferrites, unless they will be marketed with the module. The length of these lines shall b actual use or, if that length is unknown, at least 10 centimeters to insure that there is n case of the module and supporting equipment. Any accessories, peripherals, or supp connected to the module during testing shall be unmodified or commercially available . M4. The licensed module must have a FCC ID label on the module itself. That FCC visible through a window on the final device or it must be visible when an access pane easily removed. If not, a second label must be placed on the outside of the final device following text: Contains "FCC ID: xxxyyyzzz" The Grantee may either provide such a l which must be included in the application for equipment authorization, or, must provid e along with the module which explain this requirement. In the latter case, a copy of the included in the application for equipment authorization. M5. The modular transmitter must comply with any applicable RF exposure require m FCC Rules in Sections 2.1091, 2.1093 and specific Sections of Part 15, including 15.3 (f) and 15.255(g), require that Unlicensed PCS, UNII and millimeter wave devices perf environmental evaluation for RF Exposure to demonstrate compliance. In addition, sp transmitters operating under Section 15.247 are required to address RF Exposure com with Section 15.247(b)(4). Modular transmitters approved under other Sections of Par may also need to address certain RF Exposure concerns, typically by providing specif Page 1 of 3 3/7/2007http://mail.google.com/mail/?view=page&name=gp&ver=sh3fib53pgpk operating instructions for users, installers and other interested parties to ensure comp M6. The final device must be designed for mobile (> 20 cm separation) or fixed op e cm) is not permitted - Reference TCB Exclusion List (17 July 2002) II(g)]. M7. The maximum antenna gain to allow compliance with RF exposure requiremen of Certification for the module. M8. The Grant should include the following words in the device description or grant transmitter" or "transmitter module" General information about modular approvals is in FCC DA 00-1407.
