If you are unable to increase the volume on your speakers, there may be a problem with the power supply or there may be a loose connection. Follow these steps to try to resolve this issue:

  1. If applicable to your model speakers, make sure that fresh batteries are installed in the portable speakers and that the polarity is correct.

    NOTE: If your speakers are passive speakers, the power for the speakers is drawn from the connected audio device; therefore, there will be no battery compartment or AC power supply.

  2. Verify that the right speaker is securely connected to the left speaker.
  3. Make sure that the left speaker is securely connected to the LINE OUT jack of the audio playback device.
  4. If you are using passive speakers, try increasing the volume on the audio playback device.

If the issue is still unresolved, service may be required. Begin the procedure to send your Sony product into a Sony facility to be repaired.
