Menyelesaikan masalah

Q1: Cannot pair the B03Pro+ with my Bluetooth headphones or speakers.

A:

• Turn off Bluetooth on all nearby mobile phones or internal PCs to prevent automatic pairing with other devices.
• For the first pairing, ensure the distance between the B03Pro+ and your device is within 1 meter.
• If pairing still fails, perform a factory reset on both the B03Pro+ and your Bluetooth headphones/speakers.
  • To factory reset the B03Pro+, press and hold both the volume up and volume down buttons for approximately 5 seconds until all indicators flash once. The device will then enter pairing mode with flashing red and blue lights, allowing you to pair normally.

Q2: Why is there still a voice delay when using this low-latency B03Pro+ adapter with my Bluetooth headphones?

A: For true low latency, your receiving device (headphones/speakers) must also support aptX Low Latency. If the receiving device uses another codec (e.g., SBC, aptX), you might experience an audio delay of 70-200ms, which can be noticeable.

Q3: Why do the volume +/- buttons on my B03Pro+ not work in TX mode, but only in RX mode?

A: In TX mode, if you are using an optical cable for audio input, the volume +/- buttons on the B03Pro+ may not function if your connected device does not support the Audio/Video Remote Control Profile. Try switching the optical cable to a 3.5mm AUX or RCA audio cable; the volume buttons should then work.

Q4: After connecting the TV to 1Mii B03Pro+, can my Bluetooth headphones/speakers sound simultaneously with the TV's built-in speakers?

A: For many TV models, the built-in speakers may not function if you choose to use an external audio output device. This is a TV feature, and its availability depends on your TV's brand and model. However, the B03Pro+'s TX mode offers a unique "Bypass" function that allows you to share TV audio simultaneously with a wired EXTERNAL speaker/soundbar and a pair of Bluetooth headphones.

Notis Penting

• The 1Mii B03Pro+ Bluetooth Transmitter/Receiver does NOT support simultaneous transmitting and receiving functions.
• This Bluetooth adapter does not have a microphone and does NOT support online calls or conferences with a headset.
• Digital optical audio sources for transmission must be set to PCM or Stereo. Dolby/DTS input is not supported.
• aptX HD and aptX Low Latency cannot operate simultaneously; choose the best for your use case.
• If your headphones or speakers do not support aptX HD or aptX LL, the LL/HD button will have no effect.
• Not ideal for use with live music, musical instruments, or karaoke.
