Basic Operation
Power Up
Refer to Figure 39
To power-on the controller, press the ON/VR button
once. This powers up the console in Manual mode, and
also powers up the external module on the drill (if
connected).
The green LED above the button illuminates, and a
display appears showing:
set= the currently active seeding rate
Shortly thereafter the display also shows:
spd= (over 0.0 ), the current speed, and
out= 0.0 , the current system operating rate.
Once the console is powered up, the ON/VR button
toggles between Manual and VR (Variable Rate) mode.
Note: It is possible to enter all setup information with the
console connected to power, but disconnected
from the drill. Operations requiring motion, such
as calibrations, must be performed hitched (but
generate harmless errors if undertaken with only
the console powered).
Seed Rate
In Manual mode, use the ⇑/⇓ arrow buttons to set the
desired seed rate (in pounds/acre or kg/ha). Or use
FUNCTION to select Preset mode, and the
⇑/⇓ arrow
buttons to alternate between preset rates (see page 56).
In VR mode, the seed rate is set by an external “recipe”
program or external controller. The
⇑/⇓ arrow buttons can
override the current rate. VR mode is not documented in
this manual.
Power Off
Press the OFF button to shutdown.
• ON/VR button:
turns drive system on.
Press twice for VR (Variable Rate) mode.

Note: This also turns off power to the external
controller module and ground speed radar.

Presets and downloading recipes.
• ⇑/⇓ Arrow buttons

select options.

Note: ENGAGE button must also be pressed to start
drive operation.
