Setup

1. Charging the Speaker

Before first use, fully charge the speaker. Connect the supplied USB charging cable to the speaker's charging port and the other end to a USB power adapter (not included) or a computer's USB port. The charging indicator light will illuminate during charging and turn off or change color when fully charged. A full charge provides approximately 4 hours of playtime.

2. Power On/Off

• To Power On: Press and hold the power button for a few seconds until you hear an audible prompt or see the indicator light illuminate.
• To Power Off: Press and hold the power button again for a few seconds until you hear an audible prompt or the indicator light turns off.

3. Bluetooth Pairing

1. Ensure the speaker is powered on and in pairing mode. The indicator light will typically flash rapidly.
2. On your mobile device (smartphone, tablet, laptop), enable Bluetooth.
3. Search for available Bluetooth devices. You should see "ST150" or a similar name in the list.
4. Select "ST150" to connect. Once paired, the speaker will provide an audible confirmation, and the indicator light will stop flashing and remain solid.
5. The speaker will automatically reconnect to the last paired device when powered on, if the device's Bluetooth is active and within range (up to 10 meters).

4. AUX Connection

For devices without Bluetooth, use the provided AUX audio cable. Connect one end of the AUX cable to the speaker's AUX input port and the other end to the audio output jack of your device. The speaker will automatically switch to AUX mode.

Operation

Playing Audio

• Once connected via Bluetooth or AUX, start playing audio from your source device.
• Adjust the volume directly from your connected device. The speaker's control method is touch-based, but primary volume control is typically managed by the source device.

Hands-Free Calling

• When connected to a smartphone via Bluetooth, the speaker can be used for hands-free calls.
• Answering a Call: Press the multi-function button (usually the power button or a dedicated call button) once to answer an incoming call.
• Ending a Call: Press the multi-function button once to end an ongoing call.
• Rejecting a Call: Press and hold the multi-function button for a few seconds to reject an incoming call.
• Audio will be routed through the speaker, and the built-in microphone will capture your voice.

Maintenance

• Keep the speaker away from extreme temperatures, direct sunlight, and humidity.
• Clean the speaker with a soft, dry cloth. Do not use abrasive cleaners or solvents.
• Although waterproof, avoid submerging the speaker in water.
