Sorry I was kicked of somehow while giving instructions. I will begin again. Press the date key next to the arrow key. The date will pop up. Then press and hold the M+= key until the first number flashes. Enter the first digit of the month using the keyboard. The first non months will have a zero. If a zero is flashing just press zero to move on to the next space. Input that number and so on until complete. You can use the arrow key to by-pass a number that does not need to be changed. When finished, press the time button again and it will change to the Hr-Min-Sec display. Press and hold the M+= button until the first number flashes , change as needed for the hour and minutes. You will not be able to change the seconds. Last while stil in the time set mode press the # key to change to AM or PM I will have to wait till after 1PM to see how to work the 12/24 feature button for the time.
