Self-Diagnosis

Self-Diagnosis Function

When a malfunction is detected, it sounds the buzzer, the battery indicator indicates the malfunc-
tion, and the unit will stop operating. In this state, the "malfunction detail indication" will appear if
the user pushes the speed switch up or down on the controller or the forward or reverse switch
on the assistant controller. Turning OFF the power will reset the indicator.
