What does it mean when my Honda CRV beeps multiple times when I close the door and walk away?

I haven't left the lights on, and all the doors are closed. Usually it beeps twice. My owner's manual doesn't say anything about this.

Self destruct mode has been engaged

Does this happen when the engine is off? My Honda/Acura does do this as well but only when the engine is still running.

Do you have a detachable face on your CD player? If so that is probably what's beeping. You should be able to go into the settings to stop this
