• Plug your headphones into this jack for private listening. The speakers will automatically mute when headphones are connected.

4. Maintenance

To ensure the longevity and optimal performance of your Logitech S120 speakers, follow these simple maintenance guidelines:

• Cleaning: Use a soft, dry cloth to gently wipe the exterior of the speakers. Avoid using liquid cleaners, aerosols, or abrasive materials, as these can damage the finish or internal components.
• Placement: Place speakers on a stable, flat surface to prevent accidental falls. Ensure adequate ventilation around the speakers to prevent overheating.
• Cable Care: Avoid sharply bending or crimping the audio and power cables. This can damage the internal wiring and affect performance.
• Storage: If storing the speakers for an extended period, disconnect them from power and audio sources, and store them in a cool, dry place away from direct sunlight and extreme temperatures.

5. Troubleshooting

If you encounter issues with your Logitech S120 speakers, refer to the following common troubleshooting steps:

1. No Sound:
   • Ensure the speakers are powered on and the power indicator light is illuminated.
   • Check that the volume knob on the right speaker is turned up.
   • Verify that the 3.5mm audio cable is securely plugged into both the speaker and your audio source's output jack.
   • Confirm that your computer's or device's audio output is set to the correct device and the volume is not muted.
   • If headphones are plugged into the speaker's front jack, unplug them to enable sound from the speakers.
2. Distorted Sound or Buzzing:
   • Lower the volume on both the speakers and your audio source. High volume levels can cause distortion.
   • Ensure all cable connections are secure and free from damage.
   • Try moving the speakers away from other electronic devices (like monitors or power adapters) that might cause interference.
   • Test with a different audio source to determine if the issue is with the speakers or the source device.
3. Only One Speaker Working:
   • Check the 3.5mm audio cable connection. A loose connection can sometimes result in only one channel playing.
   • Ensure your audio source's balance settings are centered.
