Manufacturer: TaoTronics

CAUTION: Electrical Device. Read the safety instructions!
Use Adapter as Receiver (RX)
Step 1
Ensure that the TaoTronics TT-BA07 audio adapter* battery is fully charged and connected via the 3.5 mm audio jack to the audio system. You will have to select the “AUX” or “Line-In” jack as a source. Do not separate the two devices for more than 3 feet while pairing.
Step 2
Switch to “RX” mode (button on the side). Press and hold the Power button on the unit for approx 5 seconds. The LED will first flash blue, then flash red and blue. The receiver is now ready for pairing and can be connected with other Bluetooth enabled devices.
Step 3
Turn on the Bluetooth mode on your mobile device. It will automatically search for other Bluetooth enabled devices nearby. Choose the “TaoTronics TT-BA07” device from the list. Has the pairing been successful, the receiver’s LED will be solid blue. – In case your mobile device requests a password, please try the combination “0000”, “1111”, “8888” or “1234”.
Step 4
In case the audio receiver and the mobile devices were paired previously, it’s no more required to start pairing again since both devices will repair automatically next time. However, after a mode switch (TX to RX / RX to TX) the previous pairing setup will be deleted.
Step 5 (optional)
To pair a second device, turn off the Bluetooth mode on the already paired (first) device. Press the Power button 2 times. The audio receiver will switch back into the pairing mode. Follow again the above steps 1 to 3 for the second device. After the successful pairing, turn on the Bluetooth mode on the first device and both devices are connected simultaneously. NOTE: Only one device can stream audio. The other device must pause the streaming.

Step 2
Switch to “TX” mode (button on the side). Press and hold the Power button on the unit for approx 5 seconds until the blue LED flashes. Then press again the Power button 2 times and the red and blue LEDs will flash alternatively. The transmitter is now ready for pairing and can be connected with other Bluetooth enabled devices.

Follow again the above steps 1 to 3 for the second device. After the successful pairing, turn on the Bluetooth mode on the first device and both devices are connected simultaneously (which can take up to 30 seconds). Audio will now be streamed on both devices simultaneously.
Additional Information
Switching from the Transmitter (TX) to Receiver (RX) mode on the TT-BA07 – and vice versa – will only succeed if the adapter is switched off for at least 3 seconds. When the mode got switched, all connection settings of the previous mode are deleted and must be reset later.

- IMPRESSIVE SOUND QUALITY IS THE ULTIMATE GOAL: The High-fidelity stereo sound benefits from the 40mm neodymium driver, CSR chip, and the around-ear cushion design which provide a well-closed and immersed enviroment for your ears, Just lose yourself in the music! NOTE: Mpow 059 headphones is passive noise isolating, NOT active noise cancellation(ANC), it can't cancel the noise completely but it won't drain the battery and damage the sound. 2. The closed-back design provides immersive Hi-Fi sound with CSR chip and 40mm driver together, it is better than ANC in term of sounds quality.
- BUILT TO STAY COMFORTABLE: The Memory-protein ear cushion simulate human skin texture, ensuring lasting comfort. The stainless steel slider and softly padded headband allows you to find the perfect fit without constraint and provide excellent durability.
- NEVER POWER OFF, BOTH WIRELESS & WIRED: 1. The wireless mode: Battery update to 20-hr music time/ talking time in a single charge. A 10-minute charge gives 2 hours of play when battery is low. 2. The Wired mode: you can also use it as a wired headphone with the provided audio cable so the headphones will never power off.
