6. Penyelesaian masalah

Masalah	Kemungkinan Punca	Penyelesaian
Tiada output audio.	Incorrect mode selected; cables not properly connected; source device volume too low; paired device not connected.	Verify mode switch (TX/RX/Bypass); check all cable connections; increase volume on source and receiving devices; ensure Bluetooth device is paired and connected.
High latency (audio delay).	Receiving device does not support aptX Low Latency/Adaptive; in RX mode (low latency not supported); two devices connected simultaneously in TX mode.	Ensure both B03Pro (in TX mode) and receiving device support aptX LL/Adaptive; use only one receiving device for aptX LL; switch to TX mode for low latency.
Cannot connect to AirPods Pro 2nd Gen or AirPods Max.	Had keserasian.	The B03Pro is compatible with original AirPods but not with AirPods Pro 2nd generation or AirPods Max.
Noise/interference when powered by PC USB.	Ground loop noise from shared PC ground.	Use a separate wall adapter for power instead of PC USB.
Codec indicator shows SBC/AAC despite supporting aptX.	Receiving device does not support the desired aptX codec.	Both the B03Pro and the connected Bluetooth device must support the same advanced codec (aptX, aptX HD, aptX LL, aptX Adaptive) for it to be active.
