CHAPTER 4 - SYSTEM SETUP
System setup mode contains the options that customize the
controller to the sprayer or sprayer components. These include
calibration steps and parameters that will rarely change once
programmed.

* During speed calibration, the 844-AB will automatically sense whether a Wheel
speed or Radar speed sensor is being used.
** The number of sections available is determined within the OEM setup options.
To enter System setup mode, press and hold the Plus and Minus
keys simultaneously. While holding the Plus and Minus keys,
also press the Programme key twice (within 3 seconds) and then
release all keys to enter System setup mode.
Press and hold the Programme key for three seconds to exit
System setup mode. Changes will be saved to the console’s
memory.
NOTE: The 844-AB console will not automatically power down
during System setup mode. The system must be exited by
holding the Programme key for three seconds. A loss of
power to the controller during System setup mode will erase
all changes not previously saved to system memory.
Units of measurement
The 844-AB is capable of working in either US or SI (Standard
international metric). Use the Plus and Minus keys to switch
units. Press the Programme key to accept the value and advance
to the next programme step.
