5.2 LED Light Switch Modes

On the back of the clock, there is a switch to control the LED backlight. Select one of the following modes:

  • "O" Mode: Turns the LED light off completely.
  • "I" Mode: Activates the low-brightness LED mode when it's dark. The light will stay on for 5 hours.
  • "II" Mode: Activates the high-brightness LED mode when it's dark. The light will stay on for 5 hours.

To conserve battery life, the night light will automatically turn off after 5 hours in darkness. If the environment transitions from darkness to brightness and then back to darkness, the light will reactivate and function for an additional 5 hours.
