CHAPTER 2 - APPLICATION MODE
The 844-AB gives the possibility of working in two different ways
to fit the application. Therefore, the console should be set up and
consequent programming and working features will be dependant of
the chosen mode.
Airblast mode
This mode is designed to work with Airblast sprayers, mostly
spraying on two sides (left and right) with the possibility to switch
on or off sections in the height. The working width is defined by
the distance between two rows of trees. This mode is called AB
(airblast).

Vineyard mode
This mode is designed to work with vineyard sprayers that are
spraying horizontally. Several rows are covered and sections can be
switched on or off to adapt the working width. Each section covers
a number of faces. The working width is defined by the number of
faces and the row width.
One or more nozzles can be spraying each face. If all nozzles
spraying on a face are not equal, they should be considered as a
unique nozzle and the total flow has to be set up in the configuration
menu. But all faces have to be sprayed equally. This mode is called
HC (vineyard).

CHAPTER 3 - OEM SETUP
OEM setup mode contains the options that customize the controller
to the sprayer or sprayer components. These include calibration
steps and parameters that will never change once programmed.
ADVISORY! OEM setup parameters (except HC/AB mode) should
not be changed unless advised by TeeJet Technologies or an
authorized dealer.
To enter System setup mode, power off the console. Press and hold
the Plus and Minus keys simultaneously. While holding the
Plus and Minus keys, also press the Programme key four
times (within 3 seconds) and then release all keys to enter OEM
setup mode.
Press and hold the Programme key for three seconds to exit OEM
setup mode. Changes will be saved to the console’s memory.
Application type
As explained above, the 844-AB is capable of working in either
Airblast (AB) or Vineyard (HC) mode.
Use the Plus and Minus keys to switch from AB to HC mode.
Press the Programme key to accept the value and advance to the
next programme step.
