Pairing Steps:
This product is plug-and-play, no driver required.
A: Transmitter Mode - Red Light
1. Plug the device into a USB port for power, switch to transmitter mode (red light flashing), and it will automatically search for Bluetooth devices (e.g., Bluetooth adapter, Bluetooth headset, Bluetooth speaker).
2. Insert one end of the 3.5MM audio cable into the AUX interface of the adapter, and the other end into the audio output port of the TV, projector, tablet, MP3, CD player, or the RCA audio signal output port (Output) of the TV.
3. Turn on the Bluetooth device and set it to pairing mode. Once paired successfully, the red light will stay on.
Note:
1. For computers, it's plug-and-play without needing a driver or cable (only audio can be transmitted, not data). If there's no sound, set the sound to output from the sound card in the sound settings.
2. The pairing and connection time may vary slightly for different Bluetooth devices (e.g., Bluetooth headsets) due to differences in schemes and protocols, which is normal.
3. If pairing fails or connection takes too long, turn off all devices and try pairing again.
B: Receiver Mode - Blue Light
1. Plug the device into a USB port for power, switch to receiver mode (blue light flashing), and it will enter wireless reception mode (when powered by a computer, first insert the cable into the product, then plug the product into the computer).
2. Insert one end of the 3.5MM audio cable into the AUX interface of the adapter, and the other end into the audio input port of the playback device (e.g., headphones, speakers, car audio), or insert the 3.5 audio cable of other playback devices into the audio port of this device.
3. Turn on the Bluetooth function on your phone or tablet, automatically search for Bluetooth devices, select "RT-09" from the Bluetooth list, and click to pair. Once paired successfully, the blue light will stay on.
Note:
1. The device can also be directly plugged into the U disk interface of the player to enable Bluetooth functionality.
2. If there is no sound after successful connection, delete the paired device as there may be a Bluetooth device conflict.
