Operating Instructions

• Volume Control: Use the in-line volume control wheel located on the Dura-Cord to adjust the audio output level. Rotate the wheel upwards to increase volume and downwards to decrease it.
• Audio Playback: Once connected, audio from your device will automatically route through the headphones. Ensure your device's audio settings are configured to output sound via the USB audio device if not automatic.
• Comfort Adjustment: For prolonged use, periodically adjust the headband and earcup position to maintain comfort and prevent fatigue.

Maintenance

• Cleaning Ear Cushions: The leatherette ear cushions can be wiped clean with a damp cloth and mild soap or a non-abrasive disinfectant wipe. Ensure they are completely dry before next use. Avoid harsh chemicals.
• Cord Care: The Dura-Cord is designed for durability. Avoid excessive pulling, twisting, or sharp bending of the cord to maintain its integrity. Store the headphones neatly to prevent tangling.
• Storage: When not in use, store the headphones in a clean, dry place away from extreme temperatures and direct sunlight.

Troubleshooting

No Sound:
