5.2 Touch Controls

The earbuds feature touch-sensitive controls for various functions. Specific gestures (single tap, double tap, long press) on the left or right earbud control playback, calls, volume, and noise control modes. Refer to the quick start guide for detailed touch control mappings.

5.3 Noise Control Modes

• Active Noise Cancellation (ANC): This mode reduces ambient noise, allowing for a more focused listening experience. It is particularly effective at eliminating low and mid-frequency sounds.
• Transparency Mode: This mode uses the built-in microphones to allow external sounds to pass through, enabling you to hear your surroundings without removing the earbuds. This is useful for conversations or being aware of traffic.

Switch between ANC, Transparency Mode, and standard mode using the touch controls on the earbuds.

5.4 Power On/Off

The earbuds automatically power on when removed from the charging case and power off when placed back in the case and the lid is closed. They can also be powered on or off individually using specific touch controls, allowing for single earbud use without needing the charging case.

6. Maintenance

To ensure the longevity and optimal performance of your AVIOT TE-BD11tR earbuds, follow these maintenance guidelines:

• Cleaning: Regularly clean the ear tips and the earbud surfaces with a soft, dry cloth. For earwax buildup, gently use a small brush. Ensure charging contacts on both earbuds and case are clean and dry.
• Storage: When not in use, store the earbuds in their charging case to protect them from dust and damage.
• Water Resistance: The earbuds are IPX4 water-resistant, meaning they are protected against splashing water from any direction. They are not designed for submersion. Ensure earbuds are dry before placing them back in the charging case.
• Battery Care: Avoid exposing the battery to extreme temperatures. For long-term storage, charge the battery to approximately 50% every few months.

7. Troubleshooting

If you encounter issues with your AVIOT TE-BD11tR earbuds, refer to the following common solutions:

• Earbuds not pairing or connecting:
  • Ensure both earbuds are charged.
  • Place earbuds back in the case, close the lid, wait a few seconds, then open the lid to re-initiate pairing mode.
  • Delete "AVIOT TE-BD11tR" from your device's Bluetooth list and attempt to pair again.
  • Ensure your device's Bluetooth is enabled and within range (up to 10 meters).
• Voice prompts are in Japanese:
  • The default voice prompts for this model may be in Japanese. Check the AVIOT official website or app (if available) for any firmware updates or settings that allow language changes.
• Low battery chime/beep:

• Sound quality issues (e.g., distorted, tinny, or excessive bass):
  • Ensure the ear tips provide a good seal in your ear canal. Try different sizes of ear cushions.
  • Adjust the equalizer settings on your audio device or through a dedicated app if available.
  • Clean any debris from the earbud nozzles.
• Earbuds feel bulky or cause discomfort:
