Quick Troubleshooting

1. Soundbar Does Not Turn On

1. Check the rear ON/OFF switch.
2. Connect the charging cable to the port on the soundbar.
3. Use the cable that matches the port on your unit.
4. Connect it to a suitable USB power source and allow the speaker to charge.
5. Switch the soundbar on again.

2. Bluetooth Is Not Connecting

1. Switch on Radian.
2. Enable Bluetooth on your phone, tablet or computer.
3. Search for Radian.
4. Select it to connect.
5. If it does not appear, move the device closer and turn off other nearby Bluetooth devices that may cause interference.
6. If an old pairing is saved but will not connect, remove/forget Radian from Bluetooth settings and pair again.

3. Bluetooth Connected but No Sound

1. Confirm Radian is the selected audio output.
2. Make sure Bluetooth mode is selected.
3. Increase the volume on your source device.
4. Use the “+” button to increase speaker volume.
5. Confirm that playback is not paused.
6. Disconnect and reconnect Bluetooth if required.

4. Speaker Turns Off Automatically

The soundbar may turn off if it is not receiving a Bluetooth signal.

1. Switch it on again using the rear ON/OFF switch.
2. Reconnect your phone through Bluetooth or select another playback mode.
3. Start playback.

5. USB Playback Is Not Working

1. Check that the USB flash drive is fully inserted.
2. Confirm that it contains supported music files.
3. Press and hold “M” to select USB mode.
4. Remove and reinsert the drive.
5. Try another compatible USB drive if available.

6. Micro SD Playback Is Not Working

1. Insert the Micro SD/TF card securely.
2. Confirm that it contains supported music files.
3. Press and hold “M” to select TF/Micro SD mode.
4. Remove and reinsert the card.
5. Test another compatible card if available.

7. AUX Playback Is Not Working

1. Connect a compatible 3.5mm AUX cable to the soundbar and audio source.
2. Check that both ends are fully inserted.
3. Press and hold “M” to select AUX mode.
4. Increase the source-device volume.
5. Test another compatible cable or source if available.

8. FM Radio Does Not Scan or Reception Is Weak

1. Connect the charging cable to the charging port so it can act as an antenna.
2. Switch on Radian.
3. Press and hold “M” to select FM mode.
4. Short-press Play/Pause to start automatic scanning.
5. Wait for scanning to finish.
6. Use the track controls to move between available stations.

9. TWS Pairing Is Not Working

1. Use two Radian speakers.
2. Turn Bluetooth off on your phone or disconnect it from the first speaker.
3. Switch on both speakers.
4. Double-press the Power Button on one speaker.
5. Wait for the speakers to connect and check for blue LED indication on both units.
6. Connect your phone to Radian only after TWS pairing is complete.

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.

10. Calls Are Not Working

1. Make sure Radian is connected to the phone through Bluetooth.
2. Check that call audio is routed through the soundbar.
3. Short-press Play/Pause to answer or end a call.
4. Press and hold Play/Pause for about 2 seconds to reject an incoming call.
5. Move closer to the soundbar if the microphone sounds unclear.

11. Soundbar Does Not Charge

1. Check which charging port is present on your unit.
2. The supplied manual drawing labels the port Micro-USB; the current product listing advertises Type-C charging.
3. Use a cable that matches your unit's port; do not force the connector.
4. Check the cable and USB power source for visible damage.
5. Try another suitable USB power source if available.
6. The manual specifies charging time of up to 2.5 hours.

12. Buttons or LED Modes Do Not Work

• Play / Pause: short-press Play/Pause.

13. Battery Runtime Seems Short

1. Charge the speaker fully.
2. Test playback at a moderate volume.
3. Reduce LED lighting if it is not needed.
4. Note the playback mode and runtime if the battery drains unusually quickly.
