Belkin Corporation would like the following documents regarding this submission for FCC ID: K7SF8Z091TX to be kept confidential. 1. Schematics 2. Block diagrams The above material contains trade secrets or technical data, which would customarily be guarded from competitors. We do not want these documents to be accessible to the general public. Sincerely, Tac Pham International Regulatory Compliance Manager

Response to E05-000377-1 6 Please explain how the output power is controlled for it appears that depending upon the power class that different output powers are possible. 1. No external power amplifier (PA) is implemented in the design of DUTs (F8Z901-TX and F8Z901-RX). With the internal (PA) in the Bluetooth chip, maximum of only +6dBm is physically possible. Since Bluetooth specification for Class 1 RF transmit power range is 0 to +20 dBm, the device is rated at Class 2, as the product design intended. 2. The firmware controls the RF transmit power with level control from on- chip 6-bit DAC and maintains the transmit power to be within the Bluetooth specification for class 2 RF transmit power range (-6 to +4 dBm).

Response to E05-000377-2 1. A revised test report has been uploaded showing how the 20.8 db duty cycle correction factor was calculated.

Operational Description for TuneStage TX (F8Z901-TX) TuneStage TX is a Bluetooth v.1.2 Class 2 compliant device that functions as an A2DP (Advanced Audio Distribution Profile) source and an AVRCP (Audio Video Remote Control Protocol) target. TuneStage TX does not have an independent power source and it is powered by 3.3V power output drawn from Apple iPod. It communicates with iPod via UART and receives an analog output from iPod and digitally transmits the data to TuneStage RX or other A2DP sink devices via Bluetooth radio link. TuneStage TX implements the PCB printed meander line antenna. For TuneStage TX’s RF characteristics, please refer to Bluetooth Radio Specification (page 7 – 17). Further information can be found in the Bluetooth Specification v.1.2 available from http://www.bluetooth.org and BlueCore3-Multimedia Data Sheet available from http://www.csr.com Operational Description for TuneStage RX (F8Z901-RX) TuneStage RX is a Bluetooth v.1.2 Class 2 compliant device that functions as an A2DP (Advanced Audio Distribution Profile) sink. It is powered by 12VDC AC/DC adapter and connects to the home stereo system with RCA or 3.5mm stereo audio cable. It connects & receives digital RF data from TuneStage TX (or other A2DP source devices) via Bluetooth radio link and outputs the analog audio to the home stereo system. Antenna Specification: Normal gain – 1.5 dBi For TuneStage RX’s RF characteristics, please refer to Bluetooth Radio Specification (page 7 – 17). Further information can be found in the Bluetooth Specification v.1.2 available from http://www.bluetooth.org and BlueCore3-Multimedia Data Sheet available from http://www.csr.com Bluetooth Radio Specification 1 SCOPE Bluetooth devices operate in the unlicensed 2.4 GHz ISM (Industrial Scientific Medical) band. A frequency hop transceiver is applied to combat interference and fading. A shaped, binary FM modulation is applied to minimize transceiver complexity. The symbol rate is 1 Ms/s. For full duplex transmission, a Time- Division Duplex (TDD) scheme is used. This specification defines the requirements for a Bluetooth radio. Requirements are defined for two reasons: • Provide compatibility between radios used in the system • Define the quality of the system The Bluetooth radio shall fulfil the stated requirements under the operating conditions specified in Appendix A and Appendix B. The radio parameters shall be measured according to the methods described in the RF Test Specification. This specification is based on the established regulations for Europe, Japan and North America. The standard documents listed below are only for information, and are subject to change or revision at any time. Europe: Approval Standards: European Telecommunications Standards Institute, ETSI Documents: EN 300 328, ETS 300-826 Approval Authority: National Type Approval Authorities Japan: Approval Standards: Association of Radio Industries and Businesses, ARIB Documents: ARIB STD-T66 Approval Authority: Ministry of Post and Telecommunications, MPT. North America: Approval Standards: Federal Communications Commission, FCC, USA Documents: CFR47, Part 15, Sections 15.205, 15.209, 15.247 and 15.249 Approval Standards: Industry Canada, IC, Canada Documents: GL36 Approval Authority: FCC (USA), Industry Canada (Canada) 2 FREQUENCY BANDS AND CHANNEL ARRANGEMENT The Bluetooth system operates in the 2.4 GHz ISM band. This frequency band is 2400 - 2483.5 MHz. RF channels are spaced 1 MHz and are ordered in channel number k as shown in Table 2.1. In order to comply with out-of-band regulations in each country, a guard band is used at the lower and upper band edge. 3 TRANSMITTER CHARACTERISTICS The requirements stated in this section are given as power levels at the antenna connector of the Bluetooth device. If the device does not have a connector, a reference antenna with 0 dBi gain is assumed. Due to difficulty in measurement accuracy in radiated measurements, systems with an integral antenna should provide a temporary antenna connector during type approval. If transmitting antennas of directional gain greater than 0 dBi are used, the applicable paragraphs in EN 300 328, EN 301 489-17and FCC part 15 shall be compensated for. The device is classified into three power classes. Power class 1 device shall implement power control. The power control is used for limiting the transmitted power over +4 dBm. Power control capability under +4 dBm is optional and could be used for optimizing the power consumption and overall interference level. The power steps shall form a monotonic sequence, with a maximum step size of 8 dB and a minimum step size of 2 dB. A class 1 device with a maximum transmit power of +20 dBm shall be able to control its transmit power down to 4 dBm or less. Devices with power control capability optimizes the output power in a physical link with LMP commands (see Link Manager Protocol). It is done by measuring RSSI and reporting back if the transmission power shall be increased or decreased if possible. In a connection, the output power shall not exceed the maximum output power of power class 2 for transmitting packets if the receiving device does not support the necessary messaging for sending the power control messages, see Link Manager Protocol Section 4.1.3 on page 211. In this case, the transmitting device shall comply with the rules of a class 2 or class 3 device. If a class 1 device is paging or inquiring very close to another device, the input power can be larger than the requirement in Section 4.5 on page 39. This can cause the receiving device to fail to respond. It may therefore be useful to page at Class 2 or 3 power in addition to paging at power class 1. 3.1 MODULATION CHARACTERISTICS The Modulation is GFSK (Gaussian Frequency Shift Keying) with a bandwidthbit period product BT=0.5. The Modulation index shall be between 0.28 and 0.35. A binary one shall be represented by a positive frequency deviation, and a binary zero shall be represent…
