Notes: About the Sleep settings of Bluetooth: When the "Intelligent sleep" option is enabled, the player will automatically disconnect the Bluetooth after it enters standby, and you'll need to press the Power button to wake up the player before resuming to play; When the "Never" option is enabled, the player will never enter standby if it's connected to a Bluetooth device, and you can press the Play button on the Bluetooth device at any time to resume the playback. But this will also increase power consumption.
