When the clock reaches 2 p.m., Circuit #4 will begin turning ON for 10
seconds and OFF for 50 seconds, over and over. If you disable Program #4
(
PROGRAM 4 OFF
) you will observe that the switching stops. When you
enable the program once again (
PROGRAM 4 ON
), you will see the switching
resume, but not until the next whole minute is reached. In other words, the
program has remained
in step
with the clock while it was disabled.
