of the valve, the hitch will move to the maximum
raised position. The system will then go to Step 5.
3. To abort calibration, press either the INCR or
DECR key. The system will go to Step 11.
NOTE: If a failure is detected, the system will go to
Step 12.

The display will read ENG SPD. If the engine RPM is
at or above 1600 RPM, there will be an asterisk (*) on
the display. If there is no asterisk, increase engine
speed until the asterisk appears. Then press the
PROG key.
NOTE: If the program key is pressed without an
asterisk on the display, Cal Fail will appear on the
display and calibration cannot continue.
