It complies with the modular transmitters basic requirements (Item 1 to 8) in FCC Part 15 Subpart C Section 15.212 as indicated below: Modular Approval Checklist: Modular approval requirement Yes No (1) Have its own RF shielding. (2) Have buffered modulation/data inputs. (3) Have its own power supply regulation. (4) Comply with the antenna and transmission system requirements of § 15.203, 15.204(b) and 15.204(c). (5) Tested in a stand-alone configuration. Unless the transmitter module will be battery powered, it must comply with the AC line conducted requirements found in FCC § 15.207. AC or DC power lines and data input/output lines connected to the module must not contain ferrites, unless they will be marketed with the module. The length of these lines shall be the length typical of actual use or, if that length is unknown, at least 10 centimeters to insure that there is no coupling between the case of the module and supporting equipment. Any accessories, peripherals, or support equipment connected to the module during testing shall be unmodified and commercially available. (6) Equipped with either a permanently affixed label or must be capable of electronically displaying its FCC ID. If the FCC ID is not visible when the module is installed inside another device, then the outside of the device into which the module is installed must also display a label referring to the enclosed module. (7) Comply with any specific rules or operating requirements that ordinarily apply to a complete transmitter and the manufacturer must provide adequate instructions along with the module to explain any such requirements. (8) Comply with any applicable RF exposure requirements in its final configuration: The modular transmitter complies with FCC radiation exposure requirement. Masashi Tsuchida Mitsumi Electric Co Ltd

RF Exposure Calculations: The following inform ation provides the m inim um separation distance for the highest gain antenna provided with the “DWM-W 314“ as calculated from FCC Part 1, §1.1310, TABLE 1 (B) Limits for General Population / Uncontrolled Exposure. This calculation is based on the highest EIRP possible from the system , considering maximum power and antenna gain, and considering a 1.0mW /cm^2 uncontrolled exposure lim it. The Friis form ula used was: S = (P * G) / (4* π * r 2 ) Where P = 10 ^ ( ( specification RF power = 1dBm + tolerance 4dB ) / 10 ) = 3.16 mW (M aximum average output power with tolerance) *1) G = 0.12 Numerical Antenna gain; equal to -9.20 dBi r =20.0 cm For: DW M -W 314S = 0.00008 mW/cm 2 *1) The value is based on the specification provided by the custom er.
