Convenient ceiling projection: Our radio-controlled version projection clock allows you to project the time on the wall or ceiling with a range of 0.5 to 3 m and an adjustable angle of 180 degrees. The optimal projection distance is 1.5 to 3 m, giving you the ability to view the time from anywhere in the room. Adjustable Brightness & Dual Alarm: You can adjust the brightness of the projected time according to your preferences, ensuring a comfortable sleeping environment. The clock also has two alarms, allowing you to set two separate alarm times. Multifunctional LCD screen: The LCD screen not only displays the time but also the date, day of the week, indoor and outdoor temperature, humidity and weather forecast. This provides you with comprehensive information to improve your daily life and planning. Convenient Dual Alarm and Snooze: The clock comes with separate switches for two alarms, allowing you to set different schedules and plans. The snooze function allows you to enjoy an extra 5 to 60 minutes of sleep before the alarm sounds, simply by pressing the intuitive Snooze/Light button. Power Options and Battery Backup : Our projection clock can be powered by the included AC adapter, ensuring continuous operation and screen illumination. In the event of an unexpected power outage, the clock has a battery backup function (requires 2 AAA batteries, not included) that keeps time settings intact.
