6. Maintenance

6.1 Cleaning

To clean the clock, gently wipe the display and casing with a soft, dry cloth. Avoid using abrasive cleaners, solvents, or spray cleaners directly on the clock, as these can damage the surface or internal components.

6.2 Memory Function Battery

The clock uses one CR2032 button cell battery (not included) for memory backup. This battery preserves your time and date settings during power outages. If the clock consistently loses its settings after being unplugged, the CR2032 battery may need replacement. To replace, open the battery compartment on the back of the clock, insert a new CR2032 battery with the correct polarity, and close the compartment.

7. Troubleshooting

• Clock display is off: Ensure the USB power cable is securely connected to both the clock and the power adapter, and that the adapter is plugged into a working electrical outlet.
• Time/Date is incorrect: Follow the instructions in Section 5.1 to reset the time and date. If settings are lost after a power interruption, check or replace the CR2032 memory backup battery.
• Temperature reading seems inaccurate: The built-in temperature sensor measures indoor temperature. Ensure the clock is not placed near heat sources (e.g., direct sunlight, heating vents) or cold drafts, which can affect readings. The sensor has an accuracy of ±2°F.
• Display is too bright/dim: The clock features auto-brightness. Ensure the ambient light sensor (small dot below the time display) is not obstructed. The brightness adjusts automatically based on ambient light.
