특징
- After switching on the power supply, the blue indicator flashes and enters the Bluetooth mode; after broadcasting the "prompt tone", it enters the matching mode and waits for matching; after broadcasting the "prompt tone", the mobile Bluetooth searches for "XY-WRBT" (the name of the power amplifier board device), clicks on the "XY-WRBT" connection, and plays the "prompt tone" after the connection is successful. When the indicator lights are on for a long time, the mobile music can be played, and the indicator lights will flash slowly when the Blue The amplifier board prepares for the next pairing, and plays the "prompt sound" before entering the pairing mode to wait for the pairing.
- Cautions for Power Supply with 3.7V Lithium Battery
1. When powered by batteries, the battery voltage is less than 3.3V decoder board automatically shuts down. After re-energizing or full charging, the contacts are switched on/off for 2 seconds.
2. When using batteries for power supply, if the voltage of batteries is too low, there may be "nourishing" noise. In this case, the batteries need to be charged.
3. Because there is no charge protection circuit for lithium batteries on decoder board, it is recommended to use lithium batteries with protection board.
4. If your rechargeable battery supports Micro USB charging directly, you can use Micro USB charging directly to the battery. -

Notes for use of 3.7v lithium battery power supply
1. When using the battery power supply, the battery voltage is lower than 3.3v and the decoder board automatically shuts down. After recharging or fully charging, switch on/off contact for 2 seconds.
2. When using the battery power supply, if the battery voltage is too low, there may be "sizzling" noise, in this case, the battery needs to be charged.
3. Since no lithium battery charging protection circuit is designed on the decoding board, lithium battery with its own protection board is recommended.
4. If your rechargeable battery supports Micro USB direct charging, you can use Micro USB to directly charge the battery.
