Operating Instructions:

After the power is turned on, the blue indicator flashes quickly to enter the Bluetooth mode; After broadcasting the "prompt tone", enter the pairing mode and wait for pairing; Mobile phone Bluetooth searches for "XY-P5W" (power amplifier board device name), click "XY-P5W" to connect. After the connection is successful, "prompt tone" will be played, and the indicator light will be on for a long time to play mobile phone music. The indicator light will flash slowly when playing music; After the Bluetooth connection is disconnected, the amplifier board is ready for the next pairing, and after playing the "prompt tone", it enters the pairing mode to wait for pairing.

Precautions For Using 3.7V Lithium Battery For Power Supply:

1. When the battery is used for power supply, the decoding board automatically shuts down when the battery voltage is lower than 3.3V. It needs to be powered on again or fully charged, and then short circuit the on/off contact for 2 seconds to work normally.

2. When the battery is used for power supply, if the battery voltage is too low, "Zigzag" noise may occur. In this case, the battery needs to be charged.

3. Since no lithium battery charging protection circuit is designed on the decoding board, it is recommended to use the lithium battery with its own protection board.

4. If your rechargeable battery supports direct charging with Micro USB, you can use Micro USB to directly charge the battery.

5. The power supply should be more than 10W. It is recommended to use power supply of more than 20W. If the power supply is not enough, the sound quality will be affected.
