NOTICE
It’s unlikely that your new digital timer has any existing
programming, but to make sure, use this procedure before setting
the time.
Locate the Reset button. It is the small, round hole adjacent to the
keypad. You will need a pen or paper clip to press this button.
Press and release the Reset button. The display will light up all
the segments and then go blank.
The timer has erased all programming, displays the default
settings (
MO
, “12:00 PM”) and is ready for setup.

3 – Clear Any Existing Programming
NOTE: The time, day AND operating mode must be set before any
ON Events can be programmed. Settings for time and ON Events
will not be activated until setup and programming are complete.
Setting Time and Day
Ensure that the time is displayed. A
timer that is just reset will display
MO
, “12:00 PM”.
The first two digits (hours) of the
Time of Day (TOD) display will begin
to flash (Fig. 3).
Turn the selector wheel until the
correct hour shows in the TOD hours
display, along with the
PM
indicator,
if desired. Note that
PM
indicator will
alternate on and off as the time
passes through noon and midnight.
Press the
ON
button to set the new
hour. Or, if no change to the hour
is needed, press the
TIME
button to
keep the original hour setting. The
last two digits of the TOD display
(minutes) will begin to flash (Fig. 4).
Turn the selector wheel until the
correct time in minutes shows.
