Bluetooth 5.2 USB-A adapter with aptX LL and aptX Adaptive, wireless audio transmitter

This is a Bluetooth audio transmitter, not a receiver. It is designed for audio transmission only. Therefore, it cannot be used to connect a keyboard, mouse, or transfer files.

Please note: This product is not compatible with Mac systems.

If you use a Mac, we do not recommend purchasing this product.

This Bluetooth transmitter adds Bluetooth functionality to devices such as TVs or computers that do not have it built-in, allowing them to connect to Bluetooth speakers or headphones.

**Indicator Lights:**

* **Searching and Pairing:** Alternating red and blue flashing.

* **Connecting:** Slow blue flashing.

* **Pairing Successful:** Solid LED.

**Audio Format Indicator:**

* **SBC:** Solid blue.

* **AptX:** Solid cyan.

**Instructions for Use:**

1. **Pairing and Connecting the First Device:** When switched on, it defaults to reconnection mode (slow blue flashing). After a successful reconnection, the indicator remains solid, the color varying according to the transmission format. If no device is connected within 20 seconds, it automatically switches to search/pairing mode (alternating red/blue flashing).

2. **Pairing Another Device:** If you need to pair another Bluetooth device, switch off the first paired device, then unplug and replug the transmitter. Switch on the second Bluetooth device and put it into pairing mode for automatic connection. After successful pairing, switch the first Bluetooth device back on; the transmitter will automatically reconnect to it.

3. **Pairing Troubleshooting:**

* Check the transmitter indicator. If it is solid, it is already paired with another device. Turn off the connected receiving device, then unplug and replug the transmitter. Only when the red and blue lights flash alternately will you be able to pair it with a new Bluetooth device.

* Verify that the Bluetooth receiving device is in pairing mode.

* Move it away from potential sources of interference, such as Wi-Fi routers.

**Product Dimensions:** 17 x 7 x 15 mm.
