(Models 2302 & 2309)

To operate the Auto gage Shift-Lite
tachometer, first determine your
engine's shift point for max.
horsepower (for example, 3400 rpm).
Turn on the power to the tach. Set the
desired RPM by turning the adjust
knob on the back of the tach, the
pointer will move. Stop when it
reaches the desired shift point. Turn
the power off. The tach will now use
the selected shift point, until set differently. When the tachometer
reaches your set point, the red shift light will come on. It will stay on
until the engine speed drops below the set point.

* Note: If the engine is running, the shift point
can't be set.

* Note: The shift point setting can be checked
anytime the vehicle is started. Turn the ignition on
and the shift point setting will show on the dial.
