5. Maintenance

5.1 Cleaning

To clean the speaker, wipe it with a soft, damp cloth. Do not use abrasive cleaners or solvents, as these may damage the surface or internal components. Ensure the charging port cover is securely closed before placing the device in water.

5.2 Storage

When not in use for extended periods, store the speaker in a cool, dry place away from direct sunlight. Ensure the device is fully charged before storing to prolong battery life. The integrated sealed construction with double sealing rings effectively prevents moisture intrusion and screen fogging.

6. Troubleshooting

• Device will not power on: Ensure the battery is charged. Connect the speaker to a power source using the USB cable and try again after a few minutes.
• Cannot pair via Bluetooth: Make sure the speaker is in pairing mode (flashing LED). Ensure Bluetooth is enabled on your device and it is within range (up to 10 meters). Try unpairing and re-pairing. If TWS is active, ensure only one speaker is connected to your device.
• Inaccurate temperature readings: Ensure the thermometer probe is fully submerged in the water. Allow a few minutes for the temperature to stabilize.
• Lights are not working: Check if the device is powered on. Press the Light Mode button (✪/TWS) to cycle through modes.
• Muffled or distorted sound: Ensure the speaker is not fully submerged if playing music, as sound quality can be affected underwater. Check the volume levels on both the speaker and your connected device. If the issue persists, try disconnecting and reconnecting Bluetooth.
