Operating instructions
1. Mode control
When the decoding board is not plugged in with a USB flash drive or TF card, it defaults to Bluetooth mode when powered on; When the decoding board is plugged into a USB flash drive or TF card, it defaults to music mode when powered on; Switch modes through the MODE key or buttons on the remote control.
2. Music mode
Insert a USB flash drive or TF card to play stored audio files.
3. Bluetooth mode
Switching mode broadcast in English "THE BLUETOOOTH DEVICE IS READY TO PAIR" indicates entering Bluetooth mode and waiting for pairing; The XY-BT "found on the Bluetooth search of the mobile phone is the device name of the decoding board. When you click on the connection, the decoding board prompts" THE BLUETOOL DEVICE IS CONNECTED SUCCESSFULY ", indicating that the decoding board has successfully connected to the mobile phone and can play music.
4 USB AUDIO
USB AUDIO mode, also known as sound card mode, connects the USB AUDIO interface between the computer and the decoding board using a USB data cable. When switching modes, the prompt "USB MODE" in English means USB AUDIO mode. Open the music player on your computer to play music, and you can use the decoding board to play music from your computer; If a TF card is inserted, read and write operations can be performed on the TF card;
Attention: When using USB AUDIO mode, do not insert a USB flash drive
Matters needing attention
1. If playing on a USB flash drive, it is recommended to use USB 5V power supply (not recommended to use 3.7V lithium battery power supply), as early USB flash drives did not support 3.7V voltage
2. When using a power bank or computer, use the POWER interface instead of the USBAUDIO interface to play music from the USB drive.
3. USB flash drive or TF card, decoding board only supports FAT16/FAT32 file system, not NTFS system.
