Does the 3709 have a timer that moves every 30 seconds? If yes, how do you set it up? Thank you

Yes, the Braun 3709 has a "Professional" timer feature that emits a short, stuttering sound every 30 seconds. This reminds the user to switch to a different quadrant of the mouth. A longer stuttering sound indicates the full 2-minute brushing time recommended by dentists.
