Interface Description:
1. Power supply can use Micro-USB mobile phone charger, 3.7-4.2V lithium battery, 3.7-24V DC power supply, you can choose one of the three.
2. Short-circuit the "on/off contact" for 2 seconds to set the decoder board to on/off. For battery-powered conditions, turning off when not in use will save power and facilitate modification.
Instructions:
After the power is turned on, the blue indicator light flashes quickly and enters the Bluetooth mode; after the "prompt tone" is broadcast, it enters the pairing mode and waits for pairing; the mobile phone Bluetooth searches for "XY-WRBT" (power amplifier board device name), click "XY-WRBT" After the connection is successfully connected, the "prompt tone" will be played, the indicator light is on, and the mobile phone music can be played. The indicator flashes slowly when playing music; after the Bluetooth is disconnected, the amplifier board is ready for the next pairing and enters after the "prompt tone" is played Pairing mode is waiting for pairing.

Precautions for using 3.7V lithium battery power supply
1. When using battery power, the battery voltage is lower than 3.3V and the decoder board will automatically shut down. After re-powering or fully charged, short the on/off contact for 2 seconds to turn on.
2. When using a battery to supply power, if the battery voltage is too low, a "sizzling" noise may appear. In this case, the battery needs to be charged.
3. Since there is no lithium battery charging protection circuit on the decoder board, it is recommended to use a lithium battery with a protection board.
4. If your rechargeable battery supports Micro USB direct charging, you can use Micro USB to directly charge the battery
