ELECTRONIC INSTRUMENT CONTROL SYSTEM
The 2290, 2335, 2360, 2375 and 2425 tractors
are equipped with an Electronic Instrument
Control System designed to provide the operator
with information concerning tractor functions,
calibration procedures tomeet specific operation
requirements, and serve as a visual and audio
warning system of malfunctions that have
occurred in the tractor operating systems.
The Electronic Instrument Control System is
comprised of four dash-mounted components
and various senders and switches located
throughout the tractor. The four dash-mounted
components are identified as follows:
1 Electronic monitor digit select switch
2 Electronic monitor
3 Electronic monitor acknowledge/reset button
4 Electronic monitor rotary select switch

Electronic Monitor Digit Select Switch
The electronic monitor digit select switch is a
five-position switch used to select digits and
units of measurement during the calibration of
the electronic monitor:
Center - neutral position
Up - changes the selected digit upward between
zero and nine. Tapping the switch changes one
value at a time. Holding the switch up will roll the
numbers.
Down - changes the selected digit downward
between nine and zero. Tapping the switch
changes one value at a time. Holding the switch
down will roll the numbers.
Left - selects the next digit position to the left.
Right - selects the next digit position to the right.
The switch does not function during normal
operation of the tractor, but only when the
operator has selected the calibration mode to
program the system for specific operational
requirements.
