4.2 Powering On/Off

4.3 Bluetooth Connection
Once powered on, the speaker will automatically enter Bluetooth pairing mode. On your smartphone, tablet, or other Bluetooth-enabled device, navigate to the Bluetooth settings and search for available devices. Select 'CCYLEZ Speaker' (or a similar name) from the list to connect.
4.4 Dual Speaker Pairing (True Stereo)
For an immersive stereo experience, you can pair two CCYLEZ Bone Conduction Speakers together:
- Ensure both speakers are powered off.
- Power on both speakers simultaneously. They will automatically attempt to find and pair with each other.
- Once successfully paired, one speaker will act as the master and the other as the slave.
- Connect your device via Bluetooth to the master speaker as described in Section 4.3. Audio will now play through both speakers in stereo.
4.5 Mounting Options
The speaker offers versatile mounting options to optimize sound transmission through different surfaces:
- Suction Cup Base: The speaker is equipped with a suction cup base for stable attachment to smooth, non-porous surfaces like glass, tiles, or metal. Ensure the surface is clean and dry for optimal adhesion.
- Double-Sided Tape: For more permanent or textured surfaces, use the provided double-sided tape. Attach one side to the speaker's base and the other to your desired surface.
- Hanging Rope: Utilize the included hanging rope to suspend the speaker, allowing it to vibrate against various objects or simply hang freely.

5. Operating Instructions
Once connected via Bluetooth, you can control audio playback directly from your paired device. The speaker itself typically does not have volume or track control buttons, relying on the connected source device for these functions.
- Volume Control: Adjust the volume using the controls on your connected smartphone, tablet, or computer.
- Playback Control: Play, pause, skip tracks, or repeat using the media controls on your connected device.
- Optimal Sound: Experiment with placing the speaker on different surfaces. Hard, resonant surfaces like wooden tables, glass, or metal panels will produce distinct sound characteristics.
6. Maintenance
Proper care will extend the life of your speaker:
- Cleaning: Wipe the speaker with a soft, dry, or slightly damp cloth. Do not use harsh chemicals, abrasive cleaners, or solvents.
- Suction Cup Care: For optimal adhesion, periodically clean the suction cup base with water and allow it to air dry. Ensure the mounting surface is also clean and free of dust or grease.
- Storage: When not in use for extended periods, store the speaker in a cool, dry place, away from direct sunlight and extreme temperatures.
- Battery: To maintain battery health, avoid fully discharging the battery frequently and recharge it regularly, even if not in use.
7. Troubleshooting
If you encounter issues with your speaker, refer to the following common problems and solutions:
- No Sound:
- Ensure the speaker is powered on and fully charged.
- Verify that the speaker is successfully connected to your device via Bluetooth.
- Check the volume levels on both the speaker (if applicable) and your connected device. Ensure neither is muted.
- Try reconnecting the Bluetooth connection.
- Cannot Pair via Bluetooth:
- Ensure the speaker is in pairing mode (usually indicated by a flashing light).
- Turn off and then turn on the speaker and your device's Bluetooth.
- Move your device closer to the speaker (within 10 meters).
- Clear previous Bluetooth connections on your device and try pairing again.
- Poor Sound Quality / Distortion:
- Bone conduction sound quality is highly dependent on the surface it's placed on. Experiment with different surfaces (e.g., wood, glass, metal) to find the best sound.
- Ensure the speaker is firmly attached to the surface. Loose contact can cause distortion.
- Reduce the volume on your connected device if distortion occurs at high levels.
- Check for any physical obstructions or damage to the speaker's vibrating surface.
- Speaker Not Charging:
- Ensure the USB cable is securely connected to both the speaker and the power source.
- Try a different USB cable or power adapter.
- Verify the power source is active and providing 5V output.
