Setup
Power Supply
The KOSUMOSU ACD-430 Digital Alarm Clock requires a 5V/1A AC adapter (not included) to function. Connect the attached 1.5-meter USB-A power cable to a compatible USB power source. The included CR2025 button cell serves as a backup battery to maintain time settings during power outages, but it does not power the display.
Initial Setup
Upon first power-up or after a prolonged power outage without the backup battery, you may need to set the time and date.
