Large Digital Display The digital clock features a 9.1-inch LED display with large, clearly spaced numbers that are easy to read. You can view the time clearly from a distance and from various angles. The screen remains visible even in low-light conditions at night. 3 Alarm Modes This digital alarm clock can be placed on a desktop or mounted on a wall, offering clear visibility for adults, seniors, and children. It provides accurate time reading and includes three selectable alarm modes: - 1-5: Alarm set for Monday through Friday - 1-6: Alarm set for Monday through Saturday - 1-7: Alarm set for Monday through Sunday Adjustable Brightness and Automatic Night Mode The clock offers three levels of brightness adjustment to suit your environment. It automatically dims the display between 10:00 PM and 6:00 AM for reduced light during sleep hours. The device supports daylight saving time. 2 Groups of Alarms and Snooze Function You can set two separate alarm times. When the alarm sounds, press and hold any button for 3 seconds to turn off the alarm and proceed to the next alarm state. A short press activates the snooze function. If no action is taken within 5 seconds, the system automatically confirms and exits. Power Options The LED digital wall clock can be powered by 3 AAA batteries (not included) or via USB cable (included). When using battery power, the clock retains time memory and voice control functionality. These features are not available when using USB power only. You may choose USB power if you prefer the display to remain continuously on.
