Clock radio feature is a combination of two functions, an ALARM and a snooze ALARM. An ALARM is a sound or signal that is set to go off at a certain time, while a snooze ALARM is a feature that allows the user to temporarily turn off the ALARM for a short period of time before it goes off again. Both of these features are commonly found in clock radios, allowing users to set a specific time for the ALARM to go off and to temporarily turn it off if needed.
