4.2 Power On/Off
- To power on: Press and hold the Power button for approximately 3 seconds. An audible prompt will confirm power on.
- To power off: Press and hold the Power button for approximately 3 seconds. An audible prompt will confirm power off.
4.3 Bluetooth Pairing
The speaker uses Bluetooth 5.0 for a stable wireless connection.
- Ensure the speaker is powered on and in pairing mode (LED indicator will flash, typically blue).
- On your device (smartphone, tablet, laptop), enable Bluetooth and search for available devices.

4.4 Mounting the Speaker

- Surface Preparation: For best adhesion, ensure the surface (e.g., shower tile, mirror) is clean, dry, and smooth.
- Suction Cup Preparation: Lightly dampen the suction cup with warm water before pressing it onto the surface. Some users find applying a thin bead of petroleum jelly around the rim of the suction cup can improve long-term adhesion.
- Attachment: Press the speaker firmly against the desired surface, ensuring the suction cup creates a vacuum.
