When flashing, it indicates a "fault" condition somewhere in the control system
(see Figure 9A, Pg. 40).
The nature of the fault is indicated by the number of flashes in each burst, referred
to as the "Flash Code".
The joystick control will act differently depending on the severity of the fault and
its impact on safety. It may do one of the following:
1. Simply give a flash code as a warning and let driving continue.
2. Automatically stop the chair and indicate a fault by giving flash codes.
Transient faults may be cleared by turning the unit off then on.
Permanent faults will need to be cleared in order to resume driving.
3. Let the chair drive but at a reduced speed. This is known as Limp Mode and is
used for intermediate faults in which maintaining some degree of driving is the
preferred and safest option.
