Remove battery tray, and reinstall batteries in the opposite direction.

Verify time is set correctly including AM and PM.
Depending on timer model, refer to the appropriate instruction manual
to set the start time, duration, and run days.
Set dial to "Auto".
Turn dial to "Off" and then back to "Auto" to clear the rain delay feature.
Verify duration is set to desired time.
Confirm rubber washer/screen filter is inserted in the coupling and
tighten connection.
Cycle timer by pressing the "Water Now" button. Let timer water for

Repeat the process as needed.
