Programming Guidelines
IMPORTANT PRELIMINARY INFORMATION
Before you begin, we recommend that you review the following Programming
Guidelines that control the programming process:
■ For your convenience, the programming of the 844 has been divided
into two programming categories; System Setup Mode and Application
Setup Mode.
■ Pressing the key once will flash “”in the upper left hand corner
of the display window. The word “
USEr” will be displayed in the lower
right corner indicating you are about to enter the Application Setup
Mode. Pressing the key a second time will put the Control Console
into the Application Setup Mode. If you inadvertently press the key
once, wait for three seconds and the Control Console will return to its
normal operating mode.
■ Pressing and holding the and keys while simultaneously
pressing the key once will flash “”in the upper left hand corner
of the display window. The word “
PrO” will be displayed at the right of
the display window indicating you are about to enter the System Setup
Mode. Pressing the key a second time will put the Control Console
into the System Setup Mode. A delay of three seconds will return the
Control Console to its normal operating mode. The System Setup
programming steps will likely only need to be programmed once, to
customize the controller to your sprayer.
■ For either setup mode, if you press and hold the key for 3
seconds, your inputs will be stored and the computer will exit the
respective setup mode. This action will not be necessary until the last
programming step has been completed.
■ To increase the value of a programmable digit, press the key. To
decrease the value, press the key. These keys are located directly
to the right of the display.
For some programming steps, pressing and holding the or key
will change the programmable value rapidly. Pressing the or
key once will change the value by one increment.
Pressing the and keys simultaneously in some programming
steps will set the value to “0”.
■ For either setup mode, pressing the key will advance you to the
next programming step.
