You should be able to depress the small white button under the main display screen and have the '2004' show up on the screen. Push the big, oval button to adjust to correct year. Depress again to display the month, repeat adjustment with oval button, depress again for date, then time. Should be good to go.
My HEM 780 issimilar but, has forward and backward arrows to make adjustments.
