How can the clock display the time with only a single digit?
The clock flashes up the time in the sequence HHMM, with appropriate pauses between each digit, and a longer pause between each time cycle ie. H.H...M.M.....H.H...M.M.... and so on. It is really very intuitive, and once you 'get it', it is really obvious and simple to read the time!
