Precautions:
 
1. The decoder board supplies 3.7-5V, if it is higher than 5.5V, the chip will be burned. Do not reverse connect the positive and negative poles of the power supply. The reverse will burn the chip.
2. It is recommended that the DC power supply be 5V1A; if the power supply is insufficient, the speaker sound will be small. When the power supply is seriously insufficient, the speaker will make a “dida” sound, even without sound.
3. It is recommended to connect 2 channels of 4 ohm 3W (5W) speakers; if you connect 2 ohm speakers, the power amplifier chip will heat up, causing the chip to burn.
4. Pay attention to static electricity protection. It is easy to generate static electricity when the weather is dry. In the process of using the user, please use the static electricity on the conductor to operate the decoder board to avoid the decoder chip being destroyed by static electricity.
5. During use, the mobile phone and the bluetooth decoder board should not be blocked by obstacles such as walls, and should be kept away from the metal shield as much as possible; blocking will reduce the transmission distance, and in serious cases, the music will be stuck and intermittent; the decoder board can be properly adjusted. The angle of the phone adjusts the optimal state of the connection signal.

Instructions:
 
After the power is turned on, the blue indicator light is on and enters the Bluetooth mode; after the “Beep” is broadcast, the pairing mode is entered to wait for pairing; the mobile phone Bluetooth searches for “XY-BT” (decoding board device name), and clicks “XY-BT”. Connect, play the "Beep" after the connection is successful, you can play the phone music; after the Bluetooth is disconnected, the decoder board prepares for the next pairing, and plays the "Beep" and enters the pairing mode to wait for pairing.

Package includes:

3 x MP3 bluetooth Decoder Board
