FCC STATEMENT: 1. This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: 1)This device may not cause harmful interference. 2)This device must accept any interference received, including interference that may cause undesired operation. 2. Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. 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. Increasethe 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. RF warning statement: Thedevice has been evaluated to meet general RF exposure requirement. The device can be used in portable exposure condition without restriction.

Circuit Description Bluetooth is a short-range wireless communication technology. The design applied is in internationalidentification ISM (Industrial Scientific and Medical) frequency bandwidth environment that is2.4GHz~2.48GHz bandwidth. TheT92Bluetooth Headset is a wirelessmonoheadset manufactured with the Latest Bluetoothtechnology, complied Bluetooth specification v2.0. Within a range of 10 meters, T92Bluetoothheadset can connect to other Bluetooth devices which have built-in audio gateway, such as MobilePhone, Desktop, Notebook Computer or PDA etc. The Headset consists of the Changer Circuit, 1.8V Switched mode Regulator, Bluetooth HeadsetModule IS1601G, Audio Speaker Circuit, Microphone Bias, Status indicating LED and ThreeMultifunctionButtons for power on/off, pairing, call control, Volume Control etc. Charger Circuit The Headset are often powered internally using a 3.7 volt Lithium-ion Polymer with short circuitprotection and a capacity of 120mAh, The battery charger is based on the U2, U2 has a VCC input forthe power source from an external5.0~5.5volt DC supply. An output to the battery, Battery volt is forMicrophone Bias circuit and Bluetooth Module power 1.8V DC/DC circuit. Bluetooth module IS1601G The IC/CPU is a Class 2 Bluetooth sub-system using BlueCore2-Headset ROM chipset fromleading Bluetooth chipset supplier ISSC with a maximal output power of less than 4dBm. The moduleblock includes Bluecore02 IC, EEPROM, Band pass Filter and Crystal for clock. The RF circuit includesthe antenna matching components and a ceramic antenna welded in the circuitboard. The crystal provides the whole circuit the standard reference frequency of 16MHz. There is no externalground connection.Theground is only that of the printed circuit board. Switched mode 1.8 Volt regulator For optimum efficiency, a switch mode power supply provides the 1.8V for digital, analogue and RFportions of the device. This converter is powered from a Li-polymer battery.
