When altering an alarm on a cell phone so that instead of reading “2:37pm” (whereupon it is used to wake you from a peaceful afternoon nap) it reads “4:45am” (a time that will allow you to rise with plenty of minutes in which to shower, eat and kiss your husband before getting on a bus to the airport for a 7:50am flight), it is not sufficient to merely edit the time; if you wish actually to be woken (and thus avoid nearly missing your very small, leg-room free AirTran plane), it is necessary also to press the somewhat unobtrusive button on the phone labeled “Enable.”

Just thought you should know.
