Troubleshooting

Problem 1: Bluetooth Pairing Issues

• Solution:

1. Ensure that the SR-B7 is in pairing mode. If not, press and hold the Bluetooth button until the LED indicator starts flashing rapidly.
2. Make sure your source device (e.g., smartphone, tablet, or computer) is also in Bluetooth pairing mode.
3. Keep the source device within the recommended Bluetooth range (usually around 33 feet or 10 meters) without obstructions.
4. Clear the SR-B7’s pairing history by pressing and holding the Bluetooth button for about 8 seconds until the LED indicator alternates between red and blue. Then, try pairing again.

Problem 2: No Sound or Low Volume

• Solution:

1. Check the volume settings on both the SR-B7 receiver and your connected audio device. Ensure that the volume is turned up on both devices.
2. Verify that the audio cable connecting the SR-B7 to your audio system is securely plugged in at both ends.
3. If using a wired connection, make sure you’re using the correct input/output ports on your audio system.
4. Check if the SR-B7 has a built-in volume control. If so, adjust it to the desired level.

Problem 3: Audio Quality Issues (e.g., Distortion or Dropouts)

• Solution:

1. Ensure that the SR-B7 is within the recommended Bluetooth range and that there are minimal obstructions between the receiver and the source device.
2. Try moving the SR-B7 to a different location to minimize interference from other electronic devices or Wi-Fi networks.
3. If you are using an older Bluetooth source device, it may not support the same Bluetooth audio codecs as the SR-B7. In this case, try updating your source device’s firmware or consider using a different source device that supports more advanced codecs.
4. If possible, switch to a different audio source to see if the issue persists. This will help determine whether the problem lies with the SR-B7 or the source device.

Problem 4: Power or Charging Issues

• Solution:

1. Ensure that the SR-B7 has a sufficient battery charge. If not, connect it to a power source using the provided charging cable and adapter.
2. Allow the SR-B7 to charge for the recommended time (usually indicated in the user manual).
3. If the receiver does not power on or charge, check for loose or damaged charging cables and connections.
4. Try a different USB charging cable and power adapter to rule out potential cable or adapter issues.

Problem 5: No Response from Buttons

• Solution:

1. Check if the SR-B7 has a power switch. Ensure that it is in the “on” position.
2. Examine the buttons for any physical damage or debris that may be obstructing their operation. Clean or replace the buttons as needed.
