Operation Steps:

1.Turn it on, and then the red LED lamp and the blue LED lamp will flicker alternately until they enter paring mode, which means the device starts to work normally. Perform Bluetooth paring operations after it is on for 30 seconds.
2.After it enters paring mode, enable the Bluetooth function for the devices such as Bluetooth PC, cell phone and any other digital products with bluetooth function. Search Bluetooth devices or new devices to find SF-LY001 and connect it. Password input for paring is needed, and the default password is: 0000. 
3.After successful paring, the red LED lamp will turn off and the blue LED lamp will flicker slowly, which means it has been connected already. Then we can play music by player. 
4.To change the play device during normal operation, disconnect the connected Bluetooth PC and cell phone, and then perform paring connection for other bluetooth devices.
5.If device with battery (batteries) is selected, it is recommended to turn off it during charging. The red light is on until the charging is finished.
