1. FULL DIMMABLE DISPLAY The 3.4-inch compact LCD brightness is dial-controlled and adjustable from 0 to maximum brightness. It can be set to cast-no-glow at midnight and be bright enough to read the time from across the room during the day. The screen displays the day, 12/24 hour mode, temperature (°F or °C), and the status and ringtone for alarm 1 and alarm 2. 2. DUAL ALARMS WITH FLEXIBLE SCHEDULES Two alarms with separate weekend/weekday/all-7-day mode support varied schedules for every family. You can choose one of 5 built-in wake sounds (Beep, Piano, Buzzer, Bird, Soft Music) or use the radio as the wake-up sound. Alarm volume gradually increases from level 1 to 15. Snooze provides an additional 9 minutes of slumber. 3. MORE THAN JUST AN ALARM FM radio stores up to 40 stations for quick access. The sleep timer (10-150 minutes) lets you fall asleep with your favorite station still playing. A 3.5 mm headphone jack enables private listening without disturbing others. The clock provides 2 USB ports to charge your phone or other mobile devices while you sleep. Headphones and charging cable are not included. 4. QUICK AND EASY SETUP A large rotary dial makes setting the time and alarms fast and intuitive. All buttons and dials are clearly labeled with their function or icon, and everything is displayed on the screen for straightforward operation right out of the box. 5. BATTERY BACKUP This clock is AC-powered and can be backed up with 3 AAA batteries (not included) to restore time, settings, alarms, and radio during a power outage. USB will not charge in backup mode. Battery backup may drain batteries quickly, so use it as a backup rather than for daily operation. Practical use scenarios - Shared bedroom or busy family routines: Use the dual alarms with weekday and weekend settings to wake different members on different days. Choose a gentle wake tone or the radio with a gradual volume increase, and use the 9-minute snooze when you need a few extra minutes. - Private listening and nighttime wind-down: Listen to the radio through the clock and set a sleep timer to turn it off after you fall asleep. Use the 3.5 mm headphone jack for quiet listening without disturbing others, and charge a mobile device via the USB ports overnight. - Easy setup for all ages: The large rotary dial and clearly labeled controls enable quick setup and straightforward adjustments, even for first-time users or seniors. The dimmable display ensures comfortable viewing in any room or lighting condition.
