CRANE DOES NOT OPERATE WITH REMOTE CONTROL UNIT (CONT).
Operator will have limited visibility of load when using the manual controls. Use a
ground guide to relay signals to the operator. Boom and load moving out of control
cause serious injury or death.

move when the remote control unit is actuated.
If levers do not move, operate the crane using manual controls only and notify
Unit Maintenance when mission is completed.
