Programming the Timer can be accomplished in just a few basic steps. Before
you begin programming, it is important to install the battery, set the time of
day and date, and establish a watering plan.

Install the Batteries

The Timer requires two AA batteries to maintain the time and date in case of
AC power loss. In a typical installation, fully charged batteries should provide
sufficient power for approximately one year of operation.
Remove the terminal cover.
Insert two AA batteries into the battery compartment.
Return the terminal cover to its closed position.
Weak or missing batteries can cause the time and date to be erased after a
power failure. If this happens, you will need to install fully charged batteries
and re-enter the time and date. All other program settings will be maintained
in non-volatile memory. The display will show "LO BAT" when it is time to
replace the battery.
Set the Time of Day and Date
If this is the first time the Timer has been programmed, you should press the

Establish a Watering Schedule
To help you visualize how best to program the Timer, it might be helpful to
make a watering plan on paper. This will help you establish which days and
times you want to water.
