Selecting days of the week can be accomplished just by clicking
on them. The weekday, weekend, and everyday buttons just set 
the weekday buttons as you would expect. You can pick any
combination of days; so, for example, M,W,F,Sa is acceptable.

Instead of picking weekdays, you can pick Today or Tomorrow. The
CP-290 will not allow you to combine Today, Tomorrow, and Security
in any way (they are mutually exclusive picks.) Today events
are from the CP-290 at midnight of the day they are downloaded.
Note that X10Sched will remember when you used the Today option
and will automatically "Freeze" the time once today is
over, so things you schedule and download today won't
be downloaded again tomorrow by mistake.

When you pick a time, you specify hours:minutes, followed
by am (optional) or pm. You can use just a or p. So, 7:55p
means 7:55 pm. You can also use a twenty four hour clock
notation; 19:55 is the same as 7:55 pm. You don't use am or
pm with twenty four hour notation. You can leave off the
minutes; 8p means 8:00pm. If you don't specify am or pm,
am is assumed, so 6:30 means 6:30am.

You can also choose Sunrise or Sunset. If you do, you can 
in addition specify a number of minutes which is added to the
time of sunrise (or sunset), between -255 and 255. This
is useful if, for example, a high range of mountains to your
east makes apparent sunrise later than your latitude and 
longitude would imply. Note that, if you pick Sunrise or
Sunset, you will have to download your scripts into the
CP-290 periodically. The CP-290 does not have support
for Sunrise/Sunset calculations, and the time X10Sched
comes up with will not be valid after a few weeks.

The Security feature is supported directly by the CP-290.
In effect, this causes an event to occur, and then it reschedules
the event by adding 37 minutes to the time; if the resulting
minutes is 60 or more, it subtracts 60 from the result. So,
if you schedule a daily event for 11:20am and set Security
mode on it, it will occur at 11:20am today, 11:57am tomorrow,
11:34am the next day, and so on. If multiple units are
controlled by a time with Security mode set, they will
stay in lock step from day to day.

The Random Minute feature is supported by X10Sched, not the
CP-290, and operates differently. When X10sched sees a time
with Random Minute set, it ignores your specified minutes
value and picks a random one (00 to 59). It does this
for EACH unit the event is scheduled for, resulting in a
separately scheduled event for every unit involved. Note
that the CP-290 doesn't know the times were generated
randomly and don't continue to choose new random times
each day. But, of course, if you specify both Random Minute
and Security mode, you get the effect of the units turning 
on at different times each day, and not in lock step.

If you mix Random Minute and the Sunrise/Sunset option, 
the effect is to ADD a random number of minutes (0 to 59)
to the time chosen by the Sun code. This is not very useful
unless you download your scripts frequently, thus getting
a different random offset at intervals.

If you choose the Freeze option, the time is remembered
by X10Sched but it, and the operations scheduled with it,
are NOT sent to the CP-290. This enables you to turn
parts of scripts on and off without deleting pieces of
them.
