Motorola RAZR2 V9m

Not sure if it's the phone or the VZW UI because I'm coming from such an old phone (LG vx6000), but when you set an appointment on the calendar, it it just supposed to ring and vibrate once, or is it supposed to contionue to ring and vibrate intermittently until you acknowledge it and turn it off (ex. my flipping open the phone). On the vx6000, it would ring/vibrate for a full minute and then every few minutes if I did not shut if off.
