5. Operating Modes

5.1 Wireless Receiving Mode (RX)

In RX mode, the D600 acts as a Bluetooth receiver, allowing you to stream audio from your phone, tablet, or computer to non-Bluetooth audio systems.

1. Switch to RX Mode: Toggle the 'TX/RX' mode switch to the 'RX' position.
2. Connect to Audio System: Connect the D600's 3.5mm AUX or RCA audio output to the audio input of your target device (e.g., old speakers, car stereo, amplifier).
3. Pair with Mobile Device: Turn on Bluetooth on your mobile phone or tablet. Search for 'D600' in the list of available devices and connect.
4. Audio Playback: Once paired successfully, audio from your mobile device will play through the connected audio system.

Connecting Two Mobile Phones (RX Mode)

2. On the second mobile phone (Phone B), search for 'D600' and connect. Both phones can now stream audio to the D600, switching between them as needed.

5.2 Wireless Transmitter Mode (TX)

In TX mode, the D600 acts as a Bluetooth transmitter, allowing you to send audio from non-Bluetooth sources (e.g., TV, computer, PS5) to Bluetooth headphones or speakers.

1. Switch to TX Mode: Toggle the 'TX/RX' mode switch to the 'TX' position.
2. Connect to Audio Source: Connect the D600's 3.5mm AUX, RCA, or USB-C input to the audio output of your source device (e.g., TV, computer, game console). Note: USB-C supports TX mode audio input and charging only.
3. Enable Pairing on Receiving Device: Turn on your Bluetooth headphones or speakers and put them into pairing mode.
4. Automatic Pairing: The D600 will automatically search for and connect to the receiving device. Once paired, the indicator for the connected device (A or B) will light up.
