CL3592WH1 Digital Alarm Atomic Clock FAQ

What do “HH.H” and “LL.L” mean?

  • HH.H means the temperature is above the measurable range.
  • LL.L means the temperature is below the measurable range.

The supported temperature range is 14°F to 122°F (-10°C to 50°C).

Why are most buttons not working?

The clock may be receiving the WWVB signal. During signal reception, only the top button and RCC button are available. Wait for reception to finish or press RCC to exit.

What should I do if the clock cannot receive the WWVB signal?

Move the clock closer to a window and start another manual search by holding the RCC button. If reception is still unsuccessful, set the time and date manually through the settings menu.
