DUAL ALARM CLOCKS WITH PROJECTION ON THE CEILING: Set two separate alarms for different purposes. The time projection on the ceiling or wall is easy to see throughout the room. The recommended distance of the projection is 5 ~ 13 ft (1.5 ~ 4 m). The time is projected in a soft red color, and the clock can be rotated 180 degrees. It is convenient to view and will not disturb your sleep in the bedroom. TEMPORARY OR PERMANENT TIME PROJECTION: When powered by 2*AAA batteries (not included), pressing the top button activates the backlit LCD screen and projection for a few seconds. When using the 5V AC adapter, the backlight and projection remain continuously on. Press the snooze button to adjust among four brightness modes: bright, medium, low, and off. INDOOR THERMOMETER AND HYGROMETER: Equipped with professional sensors, this thermometer and humidity monitor provides accurate indoor temperature and humidity readings, helping you maintain a comfortable environment. SNOOZE FUNCTION: Includes a snooze feature that allows for an extra five minutes of sleep. Press any button except the top one to stop the alarm; the alarm will automatically remain active for the next day. Dual alarms, room temperature and humidity, 12/24-hour format, date, and day of the week are all displayed on the 3-inch backlit LCD screen.
