Binary count down timer

Set a count down timer in binary format! Hours in the left column, minutes in the middle and seconds in the right column. Push the menu button to set the time, push down button to reset timer. Details on how to read the time: The value of the rectangles on the bottom row is 1, the value of the rectangles on the second row from bottom is 2, the rectangles in the third row from the bottom has the value 4, and then further values are 8, 16, and 32 (only the middle column has a 32 value rectangle). To read the hours you sum the values of the white rectangles in the left column, to read the minutes you sum values of the white rectangles in the middle column and to read the seconds you sum the value of the white rectangles in the right column. Image 1 shows 1 hour, 3 minutes and 7 seconds. Image 2 shows 1 minute and 59 seconds. Image 3 shows 5 minutes.
