The requirements of section 15.212 of FCC rules have been met and shown on the following statements. The modular transmitter must have its own RF shielding. The module has its own RF shielding 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. The module has buffered data inputs integrated to Blucore4 chip The modular transmitter must have its own power supply regulation. The module has its own power supply regulation integrated to the Bluecore4 chip The modular transmitter must comply with 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 between the module and the antenna, including the cable). Any antenna used with the module must be approved The module has a unique RF coupler for an external antenna. Bluegiga Technologies Sinikalliontie 5A, P.O.

The “professional installation” provision of Section 15.203 may not be applied to modules. 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. Unless the ransmitter module will be battery powered, it must comply with the AC line conducted requirements found in Section 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 (see Section 15.27(a)). The length of these lines shall be 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 or commercially available (see Section 15.31(i)). The module was tested in a stand alone configuration using a test kit. The modular transmitter must be labeled with its own FCC ID number, and, if the FCC ID is not Please see exhibition label sample for the FCC ID of this module. And also in the Bluegiga Technologies Sinikalliontie 5A, P.O. Box 120 02630 Espoo FINLAND Tel +358 9 435 5060 | Fax +358 9 435 50660 Co ID 0934238-1, VAT registered, domicile: Espoo www.bluegiga.com | [email protected] 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. This exterior label can use wording such as the following: “Contains Transmitter Module FCC ID: XYZMODEL1” or “Contains FCC ID: XYZMODEL1.” Any similar wording that expresses the same meaning may be used. The Grantee may either provide such a label, an example of which must be included in the application for equipment authorization, or, must provide adequate instructions along with the module which explain this requirement. In the latter case, a copy of these instructions must be included in the application for equipment authorization. exhibition User manual, there are instructions to give to the OEM on how to label the end product. 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, The module is compliant with all applicable FCC rules. Detailed instructions for remaining compliance are given in the User Manual (datasheet).

Therefore WT41 provides an ideal solution for developers who want to integrate Bluetooth technology into their design. Module can be operated with batteries or DC power supply. Analysis for FCC The equipment transmits in the 2 402 – 2 480 MHz frequency range and therefore the applicable threshold is calculated as stated in FCC document KDB 447498 by using the formula f 60 (where f is a highest frequency in used) mW19.24 48.2 60 = Output power considerations: Max. E.I.R.P value: 18.08 dBm = 64.3 mW (Value is taken from the test report number: 264152-11. Value contains conducted output power and antenna gain.) RF exposure evaluation: 22 4 ... 4R PRIE R GP S  =  = E.I.R.P (dB) E.I.P.R (mW) Evaluation distance (cm) S – power density (mW/cm 2 ) 18.0864.3200.021 Analysis for IC According to standard RSS-102, RF exposure analysis is required for devices operating at or above 1.5 GHz if the maximum E.I.R.P. of the device is 5.0 W or more. Therefore RF exposure analysis is not required for this device. Result: Equipment complies with the FCC and IC limits for maximum permissible exposure

Maximum Conducted Output Power is defined as the total transmit power delivered to all antennas and antenna elements averaged across all symbols in the signalling alphabet when the transmitter is operating at its maximum power control level. Power must be summed across all antennas and antenna elements. The average must not include any time intervals during which the transmitter is off or is transmitting at a reduced power level. If multiple modes of operation are possible (e.g., alternative modulation methods), the maximum conducted output power is the highest total transmit power occurring in any mode.
