Diagnostic Trouble Code has been set in the
system memory. Refer to the Service Manual for instructions
concerning the trouble codes and trouble code retrieval.

10. Drive Orientation Indicator
When the boom is swung beyond the rear in
either direction, the Drive Orientation indica-
tor will illuminate when the drive function is
selected. This is a signal for the operator to verify that the
drive control is being operated in the proper direction (i.e.
controls reversed situations).
11. Creep Speed Indicator
When the Function Speed Control is turned to
the creep position, the indicator acts as a
reminder that all functions are set to the slow-
est speed. The light flashes if the control system puts the
machine into creep speed and will be on continuously if the
operator selects creep speed..
