Operating Instructions

- After successful Bluetooth pairing, open your music application on your device and start playback.
- Use the speaker's volume buttons (if available) or your device's volume controls to adjust the sound level.
- Use the speaker's track control buttons (if available) to skip tracks or pause/play.

3. True Wireless Stereo (TWS) Pairing
To achieve a true stereo sound experience, you can pair two Ortizan OTZ-S3 speakers together:
