Operating Instructions

3. White Noise Mode
The BLD09 speaker comes pre-installed with 36 natural and white noise sounds designed to aid sleep and relaxation.

4. Private Listening and Sound Leakage
The bone conduction design ensures that sound is primarily directed to the user, minimizing sound leakage. This allows for private listening without disturbing a sleeping partner or others in the vicinity. The sound leakage is designed to be very low, typically around 2dB to 10dB, making it suitable for shared sleeping environments.

Maintenance
Cleaning
To clean the speaker, gently wipe the surface with a soft, dry, or slightly damp cloth. Do not use abrasive cleaners, alcohol, or harsh chemicals, as these can damage the device. Ensure the charging port and TF card slot are free from dust and debris.
Storage
When not in use for extended periods, store the speaker in a cool, dry place away from direct sunlight and extreme temperatures. It is recommended to charge the battery periodically (e.g., every 3 months) to maintain battery health.
Troubleshooting
