Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: - Reorient or relocate the receiving antenna - Increase the separation between the equipment and receiver - Connect the equipment into an outlet on a circuit different from that to which the receiver is connected Consult the dealer or an experienced radio/TV technician for help. Antenna Our board type SPBT2425C2DB.xxx is for OEM integrations only. The end-user product will be professionally installed in such a manner that only the authorized antennas are used. Caution Any changes or modifications not expressed approved by the party responsible for compliance could cause the module to cease to comply with FCC rules part 15, and thus void the user’s authority to operate the equipment. Label instruction INSTRUCTION MANUAL FOR FCC ID LABELING Module type : Bluetooth class 2 board FCC-ID : S9N2425C2DB SPBT2425C2DB.xxx ( SPBT2425C2 module + PC856 carrier board) This intends to inform you how to specify the FCC ID of our Bluetooth board SPBT2425C2DB on your final product. Based on the Public Notice from FCC, the product into which our transmitter module is installed must display a label referring to the enclosed module. The label should use wording such as “Contains Transmitter module FCC ID: S9N2425C2DB or “Contains FCC ID: S9N2425C2DB, any similar wording that expressed the same meaning may be use. It shows an example below Contains FCC ID: S9N2425C2DB rev. 1.0 18-Jun-07 7/9 SPBT2425C2DB.xxx Special requirement for Modular application The following requirements are fulfilled: 1) The modular transmitter must have its own RF shielding: The RF module used on the board fulfils the emission requirements of the FCC rules without additional shielding. 2) The modular transmitter must have buffered modulation/data inputs: The module has a memory management unit inside of the IC. The processor interfacing with the external application by means general purpose I/O ( GPIO) , Uart, USB, PCM, I2C, SPI. The processor interfaces also the RF part of the module exchanging data and command with it. Inside the processor a flash memory is available to download the customer application and the Bluetooth profiles. 3) The modular transmitter must have its own power supply regulation: The module contains an own voltage regulation. In case of changes in the supply voltage VCC (for example caused by temperature changes or other effects), the internal voltage will be stabilized. 4) The modular transmitter must comply with the antenna requirements of Section 15.203 and 15.204: The RF module is for OEM (Original Equipment Manufacturer) integration only. The end-user product will be professionally installed in such a manner that only the authorized antenna is used. 5) The modular transmitter must be tested in a stand-alone configuration: The RF module was tested in a stand-alone configuration. 6) The modular transmitter must be labelled with its own FCC ID number: The RF module will be labelled with its own FCC ID number. When the module is installed inside the end-product, the label is not visible. The OEM manufacturer is instructed how to apply the exterior label. 7) 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: The EUT is compliant with all applicable FCC rules. Detail instructions are given in the product Users Guide. 8) The modular transmitter must comply with any applicable RF exposure requirements. - Maximum measured power output: 2,33 mW - Maximum antenna gain: 1 dBi = numeric gain 1,259 (see also FCC test report) Maximum permissible exposure defined in 47 CFR 1.1310: 1 mW/cm². The RF module operates at low power level so it does not exceed the Commission’s RF exposure guidelines limits; furthermore, Spread spectrum transmitters operate according to the Section 15.247 are categorically excluded from routine environmental evaluation. rev. 1.0 18-Jun-07 8/9 SPBT2425C2DB.xxx Information furnished is believed to be accurate and reliable.
