Maintenance

1. Cleaning

• Use a soft, dry cloth to clean the exterior of the headphones.
• Do not use liquid cleaners or solvents.
• The earpads can be gently wiped with a slightly damp cloth if necessary, then allowed to air dry completely.

2. Storage

• When not in use, store the headphones in the provided soft case to protect them from dust and physical damage.
• Avoid storing in areas with extreme temperatures or high humidity.

3. Battery Replacement

• Replace the AAA battery when the noise cancellation performance diminishes or the indicator light suggests low power.
• Dispose of used batteries according to local regulations.

Troubleshooting

No Sound or Low Volume

• Ensure the audio cable is securely connected to both the headphones and the audio source.
• Check the volume levels on both the headphones and your audio source.
• If using NoiseGard, ensure the battery is not depleted. Try replacing the battery.
• Test the headphones with a different audio source or cable to rule out external issues.

Noise Cancellation Not Working Effectively

• Verify that NoiseGard is switched "ON" and the battery has sufficient power.
• Ensure the earcups are properly sealed around your ears. Adjust the headband for a snug fit.
• Active noise cancellation is most effective against low-frequency, constant noises (e.g., engine hum) and less effective against sudden or high-frequency sounds (e.g., voices).
