6. Troubleshooting
If you experience issues with your Tangent Tuner II, consult the following troubleshooting guide:
| Problem | Possible Cause | Solution |
|---|---|---|
| No power | Power cable disconnected; Rear power switch off; Incorrect voltage selector setting. | Ensure power cable is securely connected. Turn the rear power switch to 'ON'. Verify the voltage selector is set correctly for your region. |
| No signal or poor reception (DAB/FM) | Antenna not connected or faulty; Weak signal area; Interference. | Check antenna connection. Try repositioning the antenna or using a higher-gain antenna. Perform a new station scan. Move unit away from other electronic devices. |
| No sound output | Audio cables disconnected; Incorrect input selected on amplifier; Amplifier volume too low. | Verify RCA or optical cables are securely connected to both the Tuner II and your amplifier. Select the correct input source on your amplifier. Increase amplifier volume. |
| Remote control not working | Batteries depleted; Obstruction between remote and unit; Remote not pointed correctly. | Replace remote control batteries. Ensure there is a clear line of sight between the remote and the Tuner II's front panel sensor. Point the remote directly at the unit. |
