Product description:.
After the device is turned on, the blue indicator flashes quickly, and the Bluetooth mode is entered. After broadcasting "beep", enter the pairing mode and wait for pairing; Mobile phone Bluetooth search "XY-P5W" (power amplifier board device name), click "XY-P5W" connection, after successful connection, play "prompt tone", long indicator light, you can play mobile phone music, when playing music, the indicator light slowly flickers; After the Bluetooth is disconnected, the amplifier board is ready for the next pairing. After entering the pairing mode, it enters the "prompt tone" to wait for pairing.
3.7V lithium battery Precautions:.
1. When battery power is used, the decoder board automatically shuts down when the battery voltage is lower than 3.3V. The on/off contacts need to be re-energized or fully charged and short for 2 seconds to work properly.
2. When using battery power, if the battery voltage is too low, there may be a "sizzling" noise. In this case, the battery needs to be recharged.
3. Since there is no lithium battery charging protection circuit on the decoder board, it is recommended to use lithium battery with protection board.
4. If your rechargeable battery supports Micro USB direct charging, you can use the Micro USB to charge the battery directly.
5. The input power must be greater than 10W. A power supply of more than 20W is recommended. If the power supply is insufficient, the sound quality will suffer.
