844E Sprayer Control
APPLICATION SETUP MODE
The Application Setup Mode contains the programming steps that are most frequently changed (target application
rate, and nozzles used). Spraying Systems Co. has added this separate setup mode to speed the programming
process when minor changes are made in the spraying operation (i.e. changing fi elds, switching nozzles,
changing crops, etc.). The operator can avoid toggling through all of the programming steps unnecessarily.
To enter the Application Setup Mode, press the key twice. Pressing the key once inadvertently will cause
the display to fl ash “ ” in the upper left and “USEr” at the lower right of the display for three seconds before
the 844 will return to normal operating mode. The “ ” / “USEr” indicates that the console is about to enter the
Application Setup Mode. Pressing the key a second time within three seconds puts the Control Console into
the Application Setup Mode.
