i notice if the alarm display is ignored the alarm stops after some number of rings. it will not ring again and eventually the time numerals change from red to the colour picked for the display. if hours can go by, with the alarm notice "cancel" "snooze" continuing to display. so even though the numeral have changed and the alarm is apparently 'off', when "snooze " is touched the display goes away and in a few seconds the numerals change to red and the alarm is reset for a four minute snooze, after which the time alarm rings again. perhaps it would be better if the snooze function continued to ring the alarm every four minutes instead. or maybe the alarm should ring every minute until snooze or cancel is pressed.
