Troubleshooting

• Clock not displaying: Ensure the power adapter is securely connected to both the clock and a working electrical outlet. Check if the power outlet is functional.
• Incorrect time: Verify Bluetooth synchronization with your phone. If manual setting is preferred, use the remote control to adjust the time.
• Remote control not working: Check the battery in the remote control. Ensure there are no obstructions between the remote and the clock.
• Display flickering (on camera): This is a common effect when LED displays are filmed due to refresh rates and is not visible to the naked eye. The clock functions normally.
• Temperature reading inaccurate: The internal temperature sensor measures the ambient temperature around the clock. External heat sources or direct sunlight can affect the reading.
