Maintenance

• Cleaning: Wipe the clock gently with a soft, dry cloth. Do not use abrasive cleaners or solvents.

• Storage: If storing the clock for an extended period, disconnect it from power and remove the memory battery.

Troubleshooting

• Clock not turning on: Ensure the USB power cable is securely connected to both the clock and a working 5V/1A USB power source.
• Clock not working on battery only: This clock is a plug-in model and requires continuous USB power for operation. The CR2032 battery is only for power-off memory, not for primary power.

• How to adjust brightness: Short press the SET button in normal time display mode to cycle through the three brightness levels.
• How to stop the two dots from flashing: The flashing dots between the hour and minute digits are a standard indicator for seconds passing or to distinguish between time and other displays. This is a design feature and cannot be stopped.
• Time/settings reset after power loss: Ensure a fresh CR2032 battery is installed in the battery compartment for the memory function.

User Tips

• For optimal performance, use a dedicated USB 5V/1A power adapter.
• The clock's sleek design makes it a great decorative piece. Consider its placement carefully to maximize its aesthetic appeal.
• If wall-mounting, ensure the chosen location has easy access to a power outlet for the USB cable.
