III,Transmitter:To Pair with Bluetooth Devices

While operating under the TX mode, the product can pair with two bluetooth devices at most, and can play music. Before the pairing,

make sure that the bluetooth audio receiver supports the A2Dp protocol. 

Paring Procedures:

1.Plug the 3.5mm audio cable into the audio jack,and connect the other end (or 2*RCA) to the output jack of the audio source.

   (such as IPod,TV and MP3,etc.)

2. Make sure that the mode switch is toggled to the TX mode.

3.The distance between the product and the bluetooth receiver shall be less than 10 meters.

4.Start up the bluetooth receiver and set it under the pairing mode.

5.The slow flashing of one blue light after the startup signifies that the product has entered the reconnecting mode under which the

   bluetooth devices connected up previously will get connected automatically.

6.If there is no re-connection 10 seconds after the startup, the two blue lights will flash fast and alternately, and the product will

   operate under the search state to search new bluetooth devices.

7.If one blue light is permanently on, it indicates that one device has been connected. The flashing of the other blue light shows that

   the second device is being searched. If the connection to the second device fails 20 seconds later, it will stop searching, and the blue

  light will stop flashing. Press the reset key gently to enter into the search mode if you want to re-search the second device. Both blue

  lights are permanently on after the product has successfully paired with two devices.


a.The search mode will last for 20 seconds. If no device is paired with the product within 20 seconds, it will enter into the stand-by

    mode which will last 5 minutes, and will automatically shut down when the stand-by mode terminates.

b.The device will try inputting "0000", "1111", "8888" and "1234" by itself to make pairing if the pairing password inputting

   is necessary.
