CHAPTER 6 - APPLICATION SETUP
Application Setup mode contains the most frequently changed setup
parameters (target application rate and nozzles used). TeeJet has
added this separate setup mode to speed the programming process
when minor changes are made during operation (e.g., changing
orchards, switching nozzles, changing crops, etc.).
To enter Application Setup mode, while in Operations mode press the
Programme key twice (within 3 seconds). One press of the
Programme key will display “PRO USER,” indicating the console
is about to enter Application Setup mode. If the Programme key is
pressed inadvertently, the console will display “PRO USER” for three
seconds before returning to Operations mode. Pressing the
Programme key a second time within 3 seconds will enter
Application Setup mode.

Calculation diagnostic
NOTE: This step is used for diagnostic purposes only. It has no
affect on the operation of the 844-AB.
This diagnostic tool will allow the operator to adjust the indicated
pressure to see what affect, if any, it would have on operating speed.
The operator can also adjust the speed to see what pressure is
required to maintain the target application rate. This process will
help determine if the correct nozzle configuration was chosen for
the application. While in the calculation step, either the pressure or
speed units will flash.
