No more oversleeping thanks to this FM Clock Radio with Dual Alarm. This alarm clock has a double alarm and a buzzer with enough volume to wake you up from your deep sleep. Would you like to turn around? Then set the snooze function so that the alarm goes off again when you turn it off. .Display too bright… then you turn the screen a little softer with the 3-step dimmer function. The alarm clock works on both mains power and on two 1.5 Volt AAA batteries. Use batteries (not included) as a backup in case of a power failure.
