5. Once paired, the TX LED will remain steady, and audio will be transmitted to your Bluetooth device.

6.2 Receiver (RX) Mode

In RX mode, the device receives audio from a Bluetooth source (e.g., smartphone, tablet) and outputs it to a non-Bluetooth audio system (e.g., wired speakers, car stereo, amplifier).

Image 4: RX Mode Compatibility

1. Switch the device to RX mode. The RX LED indicator will light up.
2. Connect the device's RX Mode Interface (3.5mm AUX OUT) to your non-Bluetooth audio system using the 3.5mm audio cable.
3. On your Bluetooth source device (e.g., smartphone), search for Bluetooth devices and select "Brifit B0CSDB3YXD" (or similar name) to pair.
4. Once paired, the RX LED will remain steady, and audio from your source device will play through your connected audio system.

7. Connecting Two Devices Simultaneously

The Brifit device supports connecting to two Bluetooth receiving devices in TX mode or pairing with two Bluetooth transmitting devices in RX mode.

6. Once both headsets are successfully paired, both TX LED indicators will remain steady.

7.2 Dual Pairing in RX Mode (e.g., two smartphones)

In RX mode, the device can be paired with two Bluetooth source devices (e.g., two smartphones), allowing you to switch between them for audio playback. Only one device can play audio at a time.

1. Ensure the Brifit device is in RX mode and connected to your audio system.
2. Pair the first Bluetooth source device (e.g., smartphone 1) with the Brifit device as described in section 6.2.
3. After successful pairing, disable Bluetooth on the first source device.
4. Pair the second Bluetooth source device (e.g., smartphone 2) with the Brifit device.
5. Once the second device is paired, re-enable Bluetooth on the first source device. The Brifit device will now be connected to both. You can switch audio playback by pausing one device and starting playback on the other.
