1. Turn the dial to the SET STATION RUN TIMES position.
2. The display will show the last program selected (A, B, C, or D). You can switch to another program by pressing the button.
3. Use the and buttons to change the station run time on the display.
4. Press the button to advance to the next station.
5. Repeat steps 4 and 5 for each station.
6. You may set station run times from 1 minute to 2 hours. If the station is assigned program D, the run time can be set for up to 12 hours.
7. You can move between programs while staying on the same station. However, it is recommended that one program is completed before going on to the next program. Jumping between programs can be confusing and may result in program errors.

NOTE: If a station is assigned a run time on program A, B, or C, then that station cannot be assigned to Program D. If this is attempted, the word USED will appear in the display. Likewise, a station with a run time on Program D cannot be assigned to program A, B, or C. This is to prevent the accidental assignment of a rotor or spray zone to the D program which is normally reserved for drip applications.
