The Holiday (HOL) Start / Stop allows a specific day(s)
to be assigned for special requirements. This is pro-
vided so that a day(s) needing special start / stop re-
quirements can be programmed without disturbing the
normal working schedule. The start / stop times for the
Holiday schedule are programmed just as any other day.
Only one start/stop time can be pro-
grammed, which will apply to each of
the Holiday days selected.
After the Enter key is pressed, a display to designate
which days of the week are holidays will appear:
*
S

T
H O L I D A Y

When the display appears, the cursor will first stop af-
ter Sunday as shown. To designate a day as a holiday,
press the " * " key. If a day marked as a holiday is not to
be a holiday, press the " * " key. When the " * " key is
pressed, the cursor will advance to the next day. Use
á
â
the

After all the holiday days are programmed, press Enter
to store the new data. The display will then return to
the beginning of the Daily Schedule (MON).
The Holiday Schedule is only per-
formed once, then erased from
memory. This avoids the need for
reprogramming after the holiday, as
most special Holiday Schedule
requirements
occasionally.
