Most ThreeH LED clocks are powered via a USB cable. The backup button battery is typically only for retaining time and alarm settings during a power outage and will not power the display.
Usually, you can press or hold the 'SET' button to enter the time-setting mode, then use the '+' or '-' buttons to toggle between 12-hour (AM/PM) and 24-hour formats as detailed in your specific user manual.
Ensure the clock is powered via the USB or AC adapter, as the projection function often does not work on battery power alone. Press the projection button to turn it on and adjust the brightness accordingly.
