Abstract: A clock radio volume control apparatus including a conventional volume control apparatus and a supplemental volume control device for use in operation of the clock radio in sleep mode at substantially reduced volume levels including electronic means for controlling whether the conventional volume control or the sleep volume control is activated based upon a timer or other sleep switch responsive to energize a relay for choosing the sleep or standard mode of operation. A delay device is included to prevent a momentary significant increase in volume at the end of the sleep period for a predetermined time to prevent awakening of a user.
