that may be either left alone or deleted.

PROGRAMMING SUMMARY
RUN MODE
Displays the current time (AM/PM format only), day of
week, and channel status as per schedule. In this mode,
the user can review all the following menus without
accidental modification:
YEAR DATE TIME
HOLIDAY
SCHEDULE
OVERRIDE
ASTRO
SET MODE
In the SET MODE, flashing LED’s guide user at the
appropriate times, to enter, change, review or delete
d a t a i n t h e f i v e m o d e s l i s t e d a b o v e . A f l a s h i n g
channel LED, for example, is asking the user to enter
a new channel # or use the one that is flashing. Also,
a pair of flashing colons are asking for data entry into
display which could be year, date, time, etc. This
feature is the keynote to programming the unit.
Another feature is that any new entry or changes
(note that data entry/change is possible in the SET
MODE) will become active only when the SET/RUN
switch is moved from SET to RUN position. However
any existing entries would continue to be executed
while the SET/RUN switch was in the SET position.
After setting schedules and other data the SET/RUN
switch is moved to the RUN position. The unit will
then execute the true status of the circuits and no
manual ON/OFF is necessary.
