6.1.3 The LED display
The LED arrow serves to visibly indicate the status of the relevant actuated valve output to
the operator. The LED arrow is a particularly useful display when the operator is located a
great distance away from the remote control and in strong sunlight.

If all of the LED arrow's LEDs flash simultaneously, a malfunction is present.
Often, these malfunctions do not involve genuine defects but indicate an attempt to operate
the vehicle under impermissible conditions.
