Liftmaster 3280 Question..

I just moved into a house that has this model garage door opener installed. No manuals or info was on hand. I keep hearing a chirping sound in my garage and believe that the sound is coming from the garage door opener as I do not have a smoke detector in this area. Does this model have a battery backup and where can I find it?
