Plug the power adapter (DC7V/700mV) to transmitter. 2. Connect the Tx set to the audio devices containing the optical/ coaxial connector by enclosed optical or coaxial cables. 3. Switch up the signal selection switch if you would connect the audio source from optical cable; Switch down the signal selection switch if you would connect the audio source from coaxial cable. 4. Turn on the power of Tx set, and the power LED indicator will light blue. 5. Turn on the power of headphone (Rx), the side blue LED will light blue. The blue LED will be flashing if the battery is in low voltage. 6. The headphone receiver is automatically searching the audio signal from Tx set. The Receiver Indicator will light green if successful connection. Notice: Notice: 1. If you hear the music intermittently, there could be some interference existing in same frequency as the Tx set. Please press the “Channel” button in front of the Txset that it will automatically transferring to the other channels for superior transmitting. 2. Please check the signal selection switch on proper position if you can not hear the sound over 30 seconds. 3. Please enjoy the music or film in effective distance. The effective transmitting distance is about 15m. There will be intermittent phenomenon if you left the Tx over the effective distance. 4. If the headphone receiver can not receive the signal from Tx normally, you could hear the continuous signal searching response from headphone. Please check if you installed the devices and connect the audio source correctly. Safety Notice Federal Communication Commission Interference Statement 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 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 Caution: Any changes or modifications not expressly approved by the party responsible…
