ThreeH support FAQ

Common questions about manuals, registration, and support for this brand.

  • Where can I download the manual for my ThreeH digital alarm clock?

    You can find, view, and download user manuals for various ThreeH alarm clocks and electronics directly on this page.

  • How do I power my ThreeH LED mirror clock?

    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.

  • How do I change the time format on my ThreeH clock to 12-hour or 24-hour?

    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.

  • Why isn't my ThreeH projection clock displaying the time on the ceiling?

    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.
