If you want a different item from the
menu, you must press and release the
push-button before four seconds have
passed. The menu items will loop
continuously. If you want to get out at this
point with no changes, stop at the last
menu item “donE”,
and in four seconds the microprocessor
will return to normal with nothing being
changed or if you are in a menu, just do
nothing for 32 seconds and the
microprocessor will restart and change
nothing.
1. The first item in the run menu is “Clr
OdO” (Clear trip odometer).
If the operator stops at this display, the
microprocessor will reset the trip
odometer to zero and will return the
microprocessor to its normal operation.
2. The second menu item “SET SPd” (Set
Speed) is used to set the speed at which
the over-speed indicator will activate.
Stopping at this display and waiting four
seconds will set the display to three digits
corresponding to the last speed that the
over-speed was set to.
The leftmost digit will be flashing and the
change and implementation of the input
numbers are the same as above. When the
push-button is held for four seconds the
microprocessor will set the number in the
display to be the new over-speed trip
point.
The option to get out with no changes is
available by not making any changes for 32
seconds.
3. The third menu feature “SELF HI” (Self
calibrate high axle) can be activated by
waiting at this display for four seconds.
This is a feature to allow automatic setting
of the high axle pulses per mile or
kilometer that the speedometer will use to
position the pointer and record the correct
mileage. This is accomplished by indicating
to the speedometer microprocessor, the
beginning and end of a measured mile or
kilometer. The microprocessor will actually
count the pulses that occurred during that
mile or kilometer and compute the required
parameters. When this mode is activated the
speedometer will display “PEndInG “.
This means that the microprocessor is
waiting for the push-button to be pressed
indicating the beginning of the measured
mile or kilometer.
When the push-button is pressed and
released the display will change to “SELF
HI” indicating that the microprocessor is
now counting pulses.
