DIAGNOSTICS
Note: SHARK is not user serviceable. Specialized tools are necessary for the repair of any SHARK com-
ponent.
INTRODUCTION
A fl ashing SHARK information gauge indicates there is an abnormal condition somewhere on the power-
chair. The components that SHARK provides fault information for include, the motor, the park brakes, the
batteries, the cabling and the SHARK modules themselves.
Note that joystick OONAPU (Out OF Neutral At Power Up) is not a fault. Simply by removing your hand
from the joystick and allowing it to return to the neutral position, the fault will immediately clear.
The nature of the abnormal condition is indicated by a fl ash code. This is a sequence of fl ashes, separated
by a pause, followed by a repetition of the sequence. The number of fl ashes relates to the condition. For
instance, four fl ashes of the SHARK information gauge, a pause, followed by four fl ashes, etc. indicates a
right motor fault. Five fl ashes would indicate a left park brake fault.
Depending on the severity of the condition, the powerchair may or may not allow driving. In some cases
the chair may be allowed to drive but in a reduced speed ("limp") mode.
DIAGNOSTICS & FAULTS
Flash codes indicate the nature of an abnormal condition directly from the
SHARK Information Gauge. Without the use of any servicing tools, the condition
can be simply diagnosed.
