SMALL BUT MIGHTY - If it takes an earthquake or siren to wake you up, this classically designed clock is ideal for heavy sleepers or individuals with hearing loss. It features a 3-level adjustable shaker that can be placed under a pillow or mattress. The vibration alarm can be used alone or combined with one of the built-in alarm sounds: buzzer, bird, or music. EASY TO SETUP - Intuitive design with clearly labeled buttons allows for simple operation right out of the box. Time and alarm settings are adjusted using the dial controls, with minimal button sharing between functions. CUSTOMIZABLE ALARM - Brightness is fully adjustable from 0 to 100% via a dial control, allowing for a dark sleeping environment. Dual alarms support different wake-up schedules for shared use. Snooze function provides an additional 9 minutes of rest. USB PORT AND BATTERY BACKUP - One USB port on the back allows charging of compatible devices overnight. Powered by AC adapter with optional backup power using 2 AAA batteries (not included) during power outages. Time, settings, and alarm functions are maintained during backup mode (vibration and USB charging are not active). 3-LEVEL ADJUSTABLE SHAKER - Offers three intensity levels: gentle, medium, and strong. Compact design fits discreetly under a pillow or mattress. Ideal for individuals who are deaf or hard of hearing, as well as those who wish to avoid disturbing others with ble alarms. DIMMABLE DISPLAY - 0-100% adjustable brightness via dial control. Can be dimmed completely for total darkness in the bedroom.
