Maintenance Features:

Power Connection: The clock requires a constant power connection via the included USB Type C cable and 5V 2A power adapter.
CR2032 Battery: The CR2032 battery is for memory settings only, ensuring the clock retains its settings (time, alarms) during a power outage. It does not power the clock independently. If the clock fails to restore the correct time after a power outage, the CR2032 battery may need replacement.
Reset Function: A "Reset" button (accessible with a needle or small stick) is provided to reset the alarm clock to its factory settings.
Temperature Sensor: The temperature sensor is pre-set inside the clock. Minor temperature differences (1-2 degrees) are normal due to internal electronic heat. If the difference exceeds 5 degrees, contact customer support for a replacement. The temperature cannot be manually reset.
Anti-Slip Bumpers: The clock comes with rubber bumper feet that can be stuck to the bottom of the device to prevent sliding.
Lifetime Warranty: The product includes a lifetime warranty service, which can be activated by visiting www.jall-us.com.
