Press the "Clock" or "Time of Day" key on your Kenmore microwave's control panel.
Push the number keys to input the time. For example, "945" or "0945" equals "9:45" on the display. If you have a microwave with a 24-hour rather than 12-hour clock, also set the time of day: touch "Enter/Start" or "Start" on the panel and then push "1" for "AM" or "2" for "PM."
Touch "Clock" or "Time of Day" again, "Enter/Start" or just "Start" to save the setting.
