Music, Volume and Light Controls

Hands-Free Calling

Radian supports phone calls over Bluetooth using its built-in microphone.

USB Playback

1. Insert a USB flash drive with supported music files into the USB port.
2. Press and hold “M” to select USB mode.
3. Use Play/Pause and the track controls to manage playback.

Micro SD Playback

1. Insert a Micro SD (TF) card containing supported music files into the card slot.
2. Press and hold “M” to select TF/Micro SD mode if playback does not start automatically.
3. Use the playback and track controls to manage music.

AUX Playback

1. Connect a compatible 3.5mm AUX cable from Radian to your phone, computer or other audio source.
2. Press and hold “M” to select AUX mode if needed.
3. Start playback on the connected device.

FM Radio

1. Connect the charging cable to the speaker's charging port to act as an antenna and improve reception.
2. Switch on Radian.
3. Press and hold “M” to select FM mode.
4. Short-press Play/Pause to start automatic channel scanning.
5. Wait for scanning to finish, then use the track controls to move between available stations.

Keep the cable connected during FM use for better reception.

TWS Stereo Pairing

TWS allows two Radian speakers to play together.

1. Turn Bluetooth off on your phone or disconnect it from the first speaker.
2. Turn on both Radian speakers.
3. Double-press the Power Button on one speaker to start TWS pairing.
4. Wait for the two speakers to connect. The manual indicates that the LEDs on both speakers flash blue after successful pairing.
5. Turn on Bluetooth on your phone and connect to Radian.
6. Start playback.

Important: TWS pairing is only guaranteed to work reliably between two Radian units from the same production batch. Pairing speakers from different batches may fail or behave inconsistently. Check the batch/date code on both units if TWS pairing doesn't work.

Charging

1. Check the charging port on your actual Radian unit.
2. Use the matching cable: the supplied manual drawing labels the port Micro-USB, while the current product listing advertises Type-C charging.
3. Connect the cable to a suitable USB power source.
4. Allow up to 2.5 hours for charging, as stated in the manual.

Do not force a connector into the port. Stop charging if the cable or port is visibly damaged.

Care & Safety

• Place the soundbar on a stable surface.
• Keep it away from water, moisture and excessive heat.
• Keep the charging port clean and dry.
• Do not force the charging connector.
• Do not use a damaged cable.
• Switch off the soundbar when not in use.
• Do not dismantle or attempt to repair a defective unit yourself.
• Avoid prolonged listening at maximum volume.
