INC-66121Wireless Headphone Emitter

Insert two AAA batteries into the battery compartmentaccording to the + and- polarity. tune the power On/Off of the receiver, then the receiver indicator will brighten. Insert two AAA batteries into the battery compartment according to the + and polarity (3.0V DC).Insertaudio plug of the emitter into AUDIO-OUT socket of audio source (such as TV set audio device PCDVD playerCD playerMP3 playeretc.). Please see Fig.1, Fig.2, Fig.3, Fig.4 ( Note: locate the emitter at a highposition in order to achieve bestreception effect) - 、 、、、、 、 () () 1Please see Fig.1, Insert the emitter audio cable into the AUDIO-OUT socket of theelectronic device or headphone socket, and move the function switch of the emitter to the“ON” position, then the emitter indicator shine. 2Built in the battery on the emitter and the receiver, draw the function switch () () () 1Connect the emitter audio cable to the adaptor cable (optional) (see Fig.2), and insert the other end of the adaptor cable into the audio out socket of the PC, then insert one end of the audio cable (optional) into the microphone socket (MIC) on theemitter, and insert the other end into the microphone in socket of the PC. 2Turn on the power switch of the emitter, then the indicator brighten, putthe out-built MIC forward yourself and keep away with the distance of 0.5M. 3open your chat tool and tune the power On/Off button , then the indicator of the headphone brighten. Adjust the volume to the suitable position, then headphone can receive the sound via the SKYPE/MSN/QQ from your friends in the other end. (see Fig.3) The receiver can be used separately as an FM radio. First draw the function switchto the “FM” position, and then press the “RESET” once, then press the “SCAN”key in turn to search a higher range and lock one radio channel; when the highest range is reached, press “RESET” key, and the frequency returns to the lowest range. Press “SCAN” key again, and the receiver will search the radio channels from thelow range again. Insert one end of the audio cable (optional) into the audio socket of the receiver (see Fig.4), and insert the other end into the headphone socket of the electronic devices, such as MP3 playerVCD playerDVD player etc., and then the unit can be used as a wired headphone. 、、、 Parts Package include Emitter Receiver(Headphone) Instruction Manual Audio cable Audio Transform cable 1 1 1 1 1 Installation Operation Wireless net audio chat Listen to the radio Wired Headphone (without batteries) Wireless headphone Installing the emitter: Installing the receiver: to the “WIRELESS” position, the receiver indicator brighten. Put the volume control to asuitable position, then adjust the tiny modulation on the emitter till getting abest effect (largest sound and clearest). Technical Specifications Emitter Emission frequency: 88.1MHz Modulation mode: FM Emission distance: 30M (with no interference) Power supply: 2xAAA batteries . Frequency range: 88.1MHz for wireless headphone and 87-108MHz for FM radio. ReceptionMode: FM Distortion: PowerSupply2xAAAbatteries 2% : Receiver(headphone) Notes To achieve best reception spread out emitter audio cable of the emitter or locate the emitter at a higher position.(the emitter audio cable can also be used as antenna). If the sound is distorted or too strong, adjust the volume of the signal source (TV setVCDplayer DVD playerPCMP3 walkman etc.) To a lower level, and reception performance may be improved. 、、、、、、 Replace the batteries if you are having the following problems The emitter indicator becomes dim. The receiver reception is poor.

Press RESET button, then press SCAN button to SCAN sound from wards automatically. 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. -- 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. FCC ID:INC-66121 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, and (2) this device must accept any interference received, including interference that may cause undesired operation.
