Hello and welcome to Just Answer. My name is ***** ***** I'll be happy to assist you today. Do you have the instructions? If not I can provide a link to them. Does the day start to flash when you press the 'set' button 2 times? If you press the 'set' button 3 times does the display change to allow you to set the leave time?
