• When the system enters low-power mode, a low battery warning will display, followed by automatic shutdown.

2. Charging via Adapter:

• Plug one end of the USB cable into a 5VDC/1A power adapter (that meets national standards and has CCC certification) and the other into the player's USB (Type-C) port.
• Under normal conditions, the device will fully charge in approximately 2–3 hours.

3. Charging via Computer USB:

• Connect the other end to the player's USB (Type-C) port to begin charging.
