Convertor

Connect the AC-to-USB adaptor between the 
power supply and the headset.  It will start 
recharging automatically.

This device can receive an audio signal from a 

compatible Bluetooth dongle, but it first needs to 

search for a dongle to pair up with.  To pair this 

device to a dongle you need to do the following:

1 – Check the device is turned OFF, then press and 

hold down the “ON/OFF” button for 5 seconds.  When 

you release the button you will see both the red and 

blue LED lights flash rapidly (around twice a second).  

This means the device is searching for a dongle to pair 

up with.  

Once the device finds a compatible dongle the red LED 

will stop flashing and the blue LED will flash more 

slowly (around once every 2 seconds).  This means it 

has paired with a compatible dongle.

2 – Turn OFF the device for at least 5 seconds (until 

you see the blue LED turn off).

3 – Turn the device ON again and it will now connect 

automatically to the dongle it was just paired with.

6. Once the headset and mobile are paired correctly the    

    red LED light will stop flashing and the blue LED light  

    will flash more slowly – around once every 2  

     

    seconds.  This means it has paired a compatible         

    mobile.

7. You now need to operate the “A2DP” function on       

    your mobile to play music (e.g. open your mobile       

    device’s music player program and select play via        

    the headset).  For more information on how to do        

    this check your mobile’s instruction manual.
