The adapter features a physical switch to change between modes. Slide the switch to the desired mode (TX for Transmitter, RX for Receiver) before connecting or pairing.

6.2. وضع الإرسال (TX)

In TX mode, the adapter transmits audio from a non-Bluetooth device to Bluetooth headphones or speakers.

1. Ensure the adapter is switched to وضع الإرسال.
2. Connect the adapter's 3.5mm audio socket to the audio output port of your non-Bluetooth device (e.g., TV, home stereo system, CD player, PC) using the provided 3.5mm audio cable or 3.5mm to 2RCA cable.
3. Turn on the adapter. The indicator light will flash, indicating it is searching for Bluetooth devices.
4. ضع سماعات الرأس أو مكبرات الصوت التي تعمل بتقنية البلوتوث في وضع الاقتران.
5. The adapter will automatically search for and connect to nearby Bluetooth audio devices. Once connected, the indicator light will change to a steady blue.

This diagram shows the adapter in Transmitter (TX) mode, connecting a non-Bluetooth audio source like a TV, computer, or MP3 player to Bluetooth headphones or a Bluetooth speaker.

ملحوظة: The adapter supports pairing with one Bluetooth receiver (headphones or speaker) at a time in TX mode.

6.3. وضع الاستقبال (RX)

In RX mode, the adapter receives audio wirelessly from a Bluetooth-enabled device and outputs it to a wired audio system (e.g., wired speakers, headphones, car stereo).

1. Ensure the adapter is switched to وضع RX.
2. Connect the adapter's 3.5mm audio socket to the audio input port of your wired stereo, speakers, or headphones using the provided 3.5mm audio cable or 3.5mm to 2RCA cable.
