The RC40 clock radio by RCA is the perfect companion in the morning. The AM/FM clock radio has a large 1.4-inch green LED display that makes it easy to see and to read. The clock can be adjusted to two different levels of brightness to accommodate for different lighting situations. The clock features automatic time set that will set the clock to one of seven different time zones once clock is plugged in. Simply flip the switch to select your current time zone. LCD display has digital frequency readout, so that you can precisely tune to your favorite radio station and read which station you are tuned in to. The programmable sleep feature will play the radio up to 2-hours before automatically turning off, allowing you to gently fall asleep to the radio. The RC40 features a 2nd display ?alarm reminder? showing the time you have set for the alarm to go off. No more second guessing if you set the time of the alarm correctly or not. It features two different alarm settings that are perfect for couples who wake at different times or for those who need a second reminder to wake in the morning. Set the alarm to wake you up to the buzzer or to your favorite radio station. Enjoy the Graduwake ramp up alarm system that gently wakes you from deep sleep by gradually increasing the volume of the alarm. You?ll no longer have a loud, rude awakening in the morning. Alarm clock features programmable snooze that you can set to ring between 1-30 minutes or by the default setting of every 9-minutes. Using the SmartSnooze feature, any of the top buttons will act as the snooze button when alarm has been activated, to ensure that you will find it when you?re half asleep. The battery backup gives reassurance that your alarm will sound even with the loss of power. The ?No Worry? battery backup keeps the clock radio working during power outages. You?ll no longer have to worry about being late to work or needing to reset the clock and alarm.
