Changing to Automatic or Manual Mode
From the run screen, toggle the control panel "AUTO" switch to put the system into automatic mode. The run screen will
show an "
A
" for each side of the boom to indicate the system is in auto. Toggling the "MANUAL" switch or a sprayer joystick
function will put the system into manual mode. The run screen will show an "

Viewing the Sensor or Target Height
When in manual mode the run screen shows the average of the sensor heights. In automatic mode the number shown on
the run screen is the target height.
Toggle "SENSOR DISPLAY" to view the actual sensor heights. The left and right sensor heights are each displayed on a
separate screen. The sensor heights are shown in either centimeters or inches depending on the sprayer type. The height
displayed is measured from the spray nozzles to the soil (soil mode) or crop canopy (crop mode).
To lock the currently viewed sensor heights on the screen indefinitely, toggle the "+" switch once. Sensor height menus
can be viewed in both automatic and manual mode.
“Table 10 - Examples of run screens” on page 39 explains some examples of typical run screens.
