Important notes and tips

This Bluetooth receiver is not a battery-powered device and is intended to connect to a power source before use. It is not designed for Bluetooth headphones and supports one active device at a time. For the most stable connection, use a 5V/1A wall adapter and avoid relying on TV or PC USB ports, which may supply insufficient power. It also features an auto‑standby function and will sleep if no audio is played for 10 minutes.
